Dry and humid air at the same temperature and pressure and volume of $1 m^{3}$ each. Select the correct statement

Options:

Answer:

Solution:

$p V = n RT \Rightarrow n = \frac{p V}{RT} =$ same $. ρ = \frac{pM}{RT}$ ; since $M_{humid} < M_{d ry}$ (water is lighter than air), $ρ_{humid} < ρ_{dry}$ .
