Question

Calculate the volume occupied by 8.8 g of CO₂ at 31.1°C and 1 bar pressure (R = 0.083 bar L K^-1 mol^-1).

Answer 1

Number of moles of CO₂ (n) = \(\frac{8.8\ g}{44\ g\ mol^{-1}} = 0.2\)

According to ideal gas equation,

pV = nRT   Or  V = \(\frac{nRT}{p}\) 

= \(\frac{0.2\ mol\times0.083\ bar\ L\ K^{-1}\ mol^{-1}\times304.25\ K}{1\ bar}\) 

=5.05L
