Calculate the volume of 99 g of CO ₂ at STP ?

Options

A22.4 L
B50.4 L
C67.2 L
D89.6 L

Correct answer

B. 50.4 L

Step-by-step solution

Molar mass of CO ₂ = 12 + 2 16 = 44 g/mol Number of moles of CO ₂ = 99 44 = 2.25 moles Volume of 1 mole of a gas at STP = 22.4 L Volume of 2.25 moles of CO ₂ = 2.25 22.4 = 50.4 L Answer: 50.4 L
