In the above equation how many moles of water can be made when 41 moles of HNO3 are consumed?
Answer:
5.125 moles of water
Explanation:
Given the reaction:
Cu + 8HNO3 --> 3 Cu(NO3)2 + 2 NO + 4 H2O
When 41 moles of HNO3 are consumed, we can calculate the number of moles of water produced using the stoichiometric coefficients in the balanced chemical equation.
According to the coefficients, 1 mole of Cu reacts with 8 moles of HNO3 to produce 4 moles of H2O. Therefore, when 41 moles of HNO3 are consumed, we can calculate the number of moles of water produced as follows:
41 moles HNO3 / 8 moles HNO3 per mole H2O = 5.125 moles H2O
So, 5.125 moles of water can be made when 41 moles of HNO3 are consumed.

Calculate the percent yield of Cl2(g) in the electrolytic decomposition of hydrogen chloride if 25.8 g of HCl produces 13.6 g of chlorine gas: 2 HCl (aq) → Cl2 (g) + H2 (g)
The percent yield of Cl2 in the electrolytic decomposition of HCl is 54.18%.
What is electrolytic decomposition?Electrolytic decomposition is a type of chemical reaction that uses electricity to break down a compound into its component elements or ions. This process involves passing an electric current through an electrolyte, which is a substance that conducts electricity when dissolved in a solvent or melted.
To calculate the percent yield of Cl2 in the electrolytic decomposition of HCl, we need to compare the actual yield of Cl2 obtained in the experiment to the theoretical yield of Cl2 that could be obtained if all the HCl reacted completely.
After balancing,
2 HCl (aq) → Cl2 (g) + H2 (g)
The molar mass of HCl is 36.46 g/mol, so 25.8 g of HCl is equal to 25.8 g / 36.46 g/mol = 0.708 mol of HCl.
According to the balanced equation, 2 moles of HCl should produce 1 mole of Cl2, so the theoretical yield of Cl2 can be calculated as:
Theoretical yield of Cl2 = 0.5 × 0.708 mol = 0.354 mol
The molar mass of Cl2 is 70.90 g/mol, so the theoretical yield of Cl2 in grams is:
Theoretical yield of Cl2 = 0.354 mol × 70.90 g/mol = 25.1 g
The actual yield of Cl2 obtained in the experiment is 13.6 g.
The percent yield of Cl2 can be calculated as:
Percent yield = (Actual yield / Theoretical yield) × 100%
Percent yield = (13.6 g / 25.1 g) × 100%
Percent yield = 54.18%

Molality of an aqueous solution of 5.0% NaCl will be 0.842 m. Mole fraction of NaCl is 0.014 and mole fraction of water is 0.98.
How do you calculate the molality of 5.0% NaCl solution?To calculate molality, we first calculate the mass of NaCl in the solution which is, 100 x 5/100% = 5g.
We then calculate the moles of NaCl in the solution,
5/58.45 = 0.08 (Molar mass of NaCl = 58.45)
Mass of water in the solution = 100g - 5g = 95g x 1/1000 = 0.095
Therefore, molality can now be calculated as,
Molality = 0.08/0.095 = 0.842 m.
How do you calculate the mole fraction of the solution?To calculate the mole fraction of the solution, we first calculate the moles of water in the solution,
Moles of water = 95/18 = 5.27 mol of water (Since molar mass of water = 18)
Now, mole fraction of NaCl = 0.08/5.27 + 0.08 = 0.014

Atomic mass of X is 813.022 g/mol and the element with an atomic mass closest to 813.022 g/mol is silver, Ag.
What is Atomic mass?
Atomic mass is the mass of an atom of a particular element, measured in atomic mass units (amu). It is equal to the sum of the number of protons and neutrons in the nucleus of an atom.
molar mass = (mass of Br) / (number of moles of Br)
molar mass = 4.742 g / (4.877 x 10-2 mol) = 974.74 g/mol
The molar mass of bromine is 80.904 g/mol, so the molar mass of the unknown metal X can be calculated as:
molar mass of X = molar mass of compound - molar mass of Br
molar mass of X = 974.74 g/mol - (3 * 80.904 g/mol) = 813.022 g/mol
The atomic mass of X can be calculated as the molar mass of X divided by the number of moles of X in the compound, which is 1:
atomic mass of X = molar mass of X / (number of moles of X)
atomic mass of X = 813.022 g/mol / 1 = 813.022 g/mol
Since the atomic mass of X is 813.022 g/mol, we can look up the element with that atomic mass in the periodic table. The element with an atomic mass closest to 813.022 g/mol is silver, Ag, with an atomic mass of 107.87 g/mol.
