How much volume would 0.450 mol CO2 gas occupy?
umka21 [38]

Answer:

10.08 L.

Explanation:

  • If we assume that CO₂ gas behaves ideally at STP (standard T(0.0 °C) and P(1.0 atm)):

<em>It is known that 1.0 mole of ideal gas occupies 22.4 L at STP conditions.</em>

<em></em>

<u><em>Using cross multiplication:</em></u>

1.0 mole of CO₂ gas occupies → 22.4 L.

0.45 mole of CO₂ gas occupies → ??? L.

<em>∴ The volume occupied by 0.45 mole of CO₂ gas </em>= (0.45 mol)(22.4 L)/(1.0 mol) = <em>10.08 L.</em>
