Answer to Question #300092 in Chemistry for Valentino

Question

A container holds 5grams of ccl4 vapour, calculate the volume of ccl4 present

Answer 1

Solution:

The molar mass of CCl₄ is 153.82 g/mol

Hence,

Moles of CCl₄ = (5 g CCl₄) × (1 mol CCl₄ / 153.82 g CCl₄) = 0.0325 mol CCl₄

At STP, one mole of any gas occupies a volume of 22.4 L.

Thus, 0.0325 mol of CCl₄ occupies:

(0.0325 mol CCl₄) × (22.4 L CCl₄ / 1 mol CCl₄) = 0.728 L CCl₄ = 728 mL CCl₄

Answer: The volume of CCl₄ is 728 mL
