Because of Avogardo Hypothesis, volumes can be used in gas phase reaction stoichiometry at constant temperature and pressure.
Avogadro's Law (also known as Avogadro's Hypothesis or Avogadro's Principle) is an experimental gas law that relates the volume of gas to the amount of gaseous matter present.
Avogadro's law states that "equal volumes of all gases at the same temperature and pressure have the same number of molecules". At constant temperature and pressure, (mol) of a gas is directly proportional.
For example, if two ideal gases, hydrogen and nitrogen, are mixed in equal amounts, they contain the same amount of molecules. This only happens if they are kept at the same pressure and temperature. This shows the ideal behavior of gases.
Let's look at this law mathematically: the overall law can be written as
V is directly proportional to n
or V = nK , K (a constant)
Amount of gas; “n” is the gaseous substance measured in moles. "k" is a constant defined for a specific pressure and temperature.
Comparing the same gas under different conditions, the law is : V₁/ n₁=V₂/ n₂
The equation shows that the number of moles of gas increases in proportion to the increase in gas volume. Therefore, the total number of atoms or molecules present in a given volume of gas is completely independent of the molar mass or size of the gas.

270g of glucose no.of molecules
Next question: 40g of ammonium nitrate
Question 1. There are [tex]9.025*10^{23}[/tex] molecules in 270g of glucose.
Question 2. There are [tex]3.009*10^{23}[/tex] molecules in 40g of glucose.
Explanation:Question 1. 270g of glucose, no. of molecules.1. Find the chemical formula of glucose.Formula: [tex]C_{6} H_{12} O_{6}[/tex]
2. Find the molar mass of this compound.Using the molar mass of each element, which can be found in the periodic table, we make the following calculations:
Molar mass of C: 12.011 u
Total mass of C in compound: (12.011 * 6)= 72.066
Molar mass of H: 1.008 u
Total mass of H in compound: (1.008 * 12)= 12.096
Molar mass of O: 15.999 u
Total mass of O in compound: (15.999 * 6)= 95.994
Why did we multiply the molar mass of C, H and O by 6, 12, and 6? This is because the formula contains 6, 12, and 6 atoms of each element, respectively.
Add up all masses:
72.066 + 12.096 + 95.994= 180.156 g/mole
This result means that 1 mole of glucose has a mass of 180.156 grams.
3. Calculate the number of molecules.Furthermore, 1 mole of any compound has a total of [tex]6.022*10^{23}[/tex] molecules. To find the amount of molecules, find the amount of moles and then the amount of molecules. Do it in the following fashion:
180.156g -----> 1 mole
270g -----------> x
[tex]\frac{270*1}{180.156} =1.499[/tex]
270 grams of glucose is the equivalent of 1.499 moles of said compound.
Now, find the number of molecules using the amount of moles calculated previously.
180.156g ----> [tex]6.022*10^{23}[/tex]
270g ---------> x
[tex]\frac{(270*6.022*10^{23} )}{180.156} =9.025*10^{23}[/tex]
4. Conclusion.There are [tex]9.025*10^{23}[/tex] molecules in 270g of glucose.
Question 2. 40g of ammonium nitrate, no. of molecules.Repeat the same process explained previously:[tex]NH_{4} NO_{3}[/tex]
N: 14.007 u
N: 14.007 u
O: (15.999 * 3)= 47.997 u
14.007 + 4.032 + 14.007 + 47.997= 80.043 g/mole
80.043g ----> [tex]6.022*10^{23}[/tex]
40g -----------> x
[tex]x=\frac{(40*6.022*10^{23}) }{80.043} =3.009*10^{23}[/tex]
There are [tex]3.009*10^{23}[/tex] molecules in 40g of glucose.

Stirring a solute into a solution increases the net dissolving rate because stirring affects how quickly a solute dissolves in a solvent but does not affect how much solute will dissolve.
The sum of solute that will break up is influenced by temperature - more will break down at higher temperatures. Typically called the solubility of the solute.
Charts of the solvency at distinctive temperatures can be utilized to decide how much will break down, or at which temperature a given arrangement will be gotten to be saturated.
Stirring moves the dissolvable particles around, permitting them to connect with the strong pieces of undissolved solute and transporting the broken-up solute absent into the bulk of the solution.
In the nonappearance of blending, the concentration of solute will be most noteworthy near the pieces of solute, so more solute won't break down into the arrangement until the broken-up solute has been transported absent by dissemination.

the fat, tripalmitin, when hydrolyzed with aqueous naoh followed by acidification with hcl yields glycerol and palmitic acid. if 0.018 mol of tripalmitin is hydrolyzed, what is the theoretical yield of palmitic acid in moles?
When 0.018 mol of tripalmitin is hydrolyzed, the theoretical yield of palmitic acid will be 0.054 moles.
The hydrolysis of tripalmitin with NaOH is saponification where a glycerol compound and fatty acids are released. Thus the fatty acids combined with the Na ion further react with the acid HCl forming a salt. Tripalmitin is a triglyceride obtained from 3 hydroxy groups of glycerol by palmitic acid (hexadecanoic). Thus, this hydrolysis yield carboxylate salt and alcohol called a saponification reaction.

The polarity equation is given, masks are divided by smaller mosques, and all are divided by the volume of solution in liters.
As a result, we will obtain a number closer to 1.49. Thus, the original solution's polarity is as follows.
What is the meaning of Molarity ?The amount of a substance in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. Molarity is defined as the number of moles of solute per liter of solution.
The moles of solute per liter of solution is measured as molarity. For instance, when table salt is dissolved in water, water serves as both the solution and the solute. Sodium chloride weights 58.44 grams per mole. One liter of water and 58.44 grams of sodium chloride combine to form one molar solution, or 1M.
100 g of a solution Additionally, it is assumed that the starting density is 1.02 grandpa. We can therefore determine the volume or solution from this information. Volume of the solution is therefore equal to the solution's mass divided by its city. So we have 100 g of solutions here. Therefore, 100 g make up the majority of the solution. Divided by the solution's density, 1.02 grandpa is obtained. The result will be 98.04 cm. The volume motor solution is now available. Next, we may determine the initial solution's polarity.

Magnesium carbonate (MgCO3) is basic in nature and insoluble in water but when 0.1m HNO3 (acidic) is added the MgCO3 will dissociate due to the opposite nature that is MgCO3 is basic and HNO3 is acidic. This will lead to an increase in solubility. The balanced equation of this reaction is:
MgCO 3 (s) + 2 HNO 3 (aq) → Mg(NO 3) 2 (aq) + CO 2 (g) + H 2O (l)
The equilibrium constant for the dissolution of a solid substance into an aqueous solution is the solubility product constant. Ksp is used to represent it.
A type of equilibrium constant, the solubility product's value changes with temperature. Due to increasing solubility, Ksp often rises as temperature rises.
A substance's ability to dissolve in a solvent to create a solution is known as a substance's solubility.
