The vapour density of a gas is 22. of this gas at STP occupies: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
The vapour density of a gas is 22. $11 \text{ g}$ of this gas at STP occupies:
Answer: B
💡 Solution & Explanation
$\text{MW} = 2 \times 22 = 44 \text{ g/mol}$. <br>$\text{Moles} = 11 / 44 = 0.25 \text{ mol}$. <br>$\text{Volume} = 0.25 \times 22.4 = 5.6 \text{ L}$.
