Answer 2

Answer:

The vapor density of unknown gas is equal to 32.

Explanation:

The relation for vapor density is : molecular mass of a gas is twice of  the vapor density of that gas.

Molecular mass = 2× vapor density

vapor density of gas = (Molecular mass)/2

Given at STP, 5.6L of gas has mass = 16g

1 liter of gas has mass $=\frac{16}{5.6} g$

22.4L of gas has mass $=\frac{16}{5.6}*22.4=64g$

22.4 L of gas has molecular mass $=64g$

Therefore the vapor density of that gas $=\frac{64}{2}=32$

Therefore, at STP vapor density of gas will be equal to 32.
