Question

Calculate the density of $C O_{2}$ at $100^{0} C$ and 800 mm Hg pressure.

Open in App

Solution

As, $d = \frac{P M}{R T}$

where $p = \frac{800}{760}$ atm

$T = 272 + 100 = 373 K$

$R = 0.0821$ L atm K $^{- 1}$ mol $^{- 1}$

$m_{c o_{2}} = 44$

$∴ d = \frac{800 \times 44}{760 \times 0. 0.821 \times 373}$

$d = 1.5124$ g/L
