A 0.250 g sample believed to be copper (Ii) acetate monoydrate required 11.84 mL of 0.105 M Na2S2O3 to reach the endpoint in an iodometric titration. Calculate the experimental percent by mass of copper in the sample and the theoretical mass percent of copper in copper (II) acetate monohydrate.
The mass percent of copper is 28.45 %. In , there are 1 copper atom and 2 bromine atoms.
How do you find the mass percent of copper?To get the mass percent of an element in a compound, multiply the result by 100 after dividing the mass of the element in 1 mole of the compound by the compound's molar mass. In , there are 1 copper atom and 2 bromine atoms.Mass percent = (mass of chemical / total mass of compound) x 100 is the formula for the mass percent of a compound.
Mass of copper= 63.54 g
Mass of copper bromide = 223.37 g
Putting values in above equation, we get:
mass of percentage copper = 63.54/223.37*100
= 28.45%

What is Ideal gas law?
The relationship between a gas's pressure P, volume V, and temperature T in the range of low pressures and high temperatures, when the gas's molecules move virtually independently of one another, is known as the ideal gas law, also known as the perfect gas law. In this situation, the ideal gas law, often known as an equation of state, governs all gases: The universal (or perfect) gas constant, 8.31446261815324 joules per kelvin per mole, and n, the number of moles of the gas, are the two inputs into the formula PV, which equals nRT. The Boltzmann constant k multiplied by Avogadro's number NA yields the universal gas constant.
The International System of Units uses the units of joules, cubic metres (m3), newtons (N), pascals (Pa), and newtons per square metre (N/m2) to measure energy, volume, force, and pressure. One joule of work is produced for every newton of force travelling over a distance of one metre. As a result, the work dimensions are the same for both products, PV and nRT (energy).

A sample of argon gas at stp occupies 56. 2 liters. Determine the mass of argon in the sample.
Answer:
[tex] \huge{\boxed{100.4 \: g}} [/tex]
Explanation:
In order to find the mass of the gas we must first find the number of moles of the gas at STP ( standard temperature and pressure) and use it together with the molar mass of the gas.
In order to find the number of moles from the volume given we use the formula;
[tex] n = \frac{V}{v_{m}}\\[/tex]
where
V is the volume of the gas
n is the number of moles
v(m) is the molar gas volume at stp which is
22.4 L/mol
From the question
V = 56.2 L
We have;
[tex] n = \frac{56.2}{22.4} = 2.508 \\ [/tex]
n = 2.51 moles
Now we use the formula m = M × n to find the mass of the gas
where
m is the mass
M is the molar mass
Molar mass of Argon = 40 g/mol
We have
m = 40 × 2.51 =. 100.4
We have the final answer as:
100.4 gif the amount of 2-naphthol used in this reaction was doubled, would the reaction rate be different? if so, how and why?
First order in the substrate and first order in the nucleophile define the rate of an SN2 reaction. The reaction rate doubles with a doubling of the substrate concentration. The rate also doubles when the concentration of the nucleophile is increased.

Alternatively, the reaction rate doubles when the concentration is increased. The decomposition reaction is an example of a first-order reaction with one or two reactants.Depending on the concentration of one of the reactants, a first-order reaction rate will occur.

The atomic mass of an element is the average mass of the element's atoms measured in atomic mass units. Atomic mass is the weighted average of all isotopes of that element, the mass of each isotope multiplied by the abundance of that particular isotope.
An atom is any particle of the most elementary level of matter that contains at least one proton. Here are some examples of atoms. Atomic mass indicates the size of an atom. Mass is technically the sum of the masses of all protons neutrons and electrons in an atom but the mass of electrons is much less than the mass of other particles so the mass is simply the mass of the nucleus.
