Volume Occupying STP

Question

What volume does 1.5 x 10²⁴ molecules of CO₂ occupy at STP?

Answer 1

One mole of any gas will occupy 22.4 liters at STP conditions. 1.0 mole = 22.4 L

and 1.0 mole = 6.02 x 10²³ molecules

1.5 x 10²⁴ molecules x 1.0 mole / 6.02 x 10²³ molecules x 22.4 L / 1.0 mole = 56 L
