How do you determine the density of water vapor at different temperatures?

Open in App

Solution

Considering water vapor as an ideal gas and applying the Ideal Gas equation to find the density of water vapor.

$∵ P V = n R T$
$\Rightarrow P \times V = \frac{m}{M} \times R \times T$

$\Rightarrow \frac{m}{V} = \frac{P \times M}{R \times T}$

$\Rightarrow ρ = \frac{P \times M}{R \times T}$
