Answer to Question #346576 in General Chemistry for Han

Question

In the chemical reaction below, how many grams of HCl will be lrodiced by the reaction 2343.42g of CCl4? Show the solution.

CCl4 + 2HF -------> CCl2F2 + 2HCl

Answer 1

Solution:

The molar mass of CCl₄ is 153.82 g/mol

Therefore,

Moles of CCl₄ = (2343.42 g CCl₄) × (1 mol CCl₄ / 153.82 g CCl₄) = 15.2348 mol CCl₄

Balanced chemical equation:

CCl₄ + 2HF → CCl₂F₂ + 2HCl

According to stoichiometry:

1 mol of CCl₄ produces 2 mol of HCl

Thus, 15.2348 mol of CCl₄ produce:

(15.2348 mol CCl₄) × (2 mol HCl / 1 mol CCl₄) = 30.4696 mol HCl

The molar mass of HCl is 36.458 g/mol

Therefore,

Mass of HCl = (30.4696 mol HCl) × (36.458 g HCl / 1 mol HCl) = 1110.86 g HCl

Answer: 1110.86 grams of HCl will be prodiced by the reaction.
