Problem: A sample of N2 O gas has a density of 2.90 g/L at 298 K.What must be the pressure of the gas (in mmHg)?

FREE Expert Solution

We will derive the density from the ideal gas law equation:

$PV = nRT$

$\frac{P V}{V} = \frac{nRT}{V} P = \frac{n RT}{V}$

$n = \frac{mass (m)}{molar mass (M)}$

$P = \frac{m RT}{M V}$

$\frac{m}{V} = \frac{g}{L} = density (d)$

$P (M) = \frac{d RT}{M} (M) \frac{PM}{RT} = \frac{d RT}{RT} d = \frac{PM}{RT}$
