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

From the given question, in order to calculate the volume occupied by carbon dioxide, we need to use the ideal gas equation.

In the ideal gas equation, we need to substitute the number of moles of carbon dioxide which could be calculated from the given weight of carbon dioxide which is 8.8 g, the given pressure is 1 bar and the gas is at a temperature 0˚C which again needs to be converted into Kelvin(k).

The volume of carbon dioxide at a given conditions can be calculated as follows ,

                                                   PV=nRT

$V=\frac{8.8}{44} \times 0.083\times \frac{(273+31.1)}{1}$

       V = 5.048 bar
