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 gas equation,
PV = (w/M)RT
Where w = mass of the gas. M = molar mass of the gas. For CO₂, M = 44 g/mol Substituting the given values ,we get
l × V = (R8/44) × 0.083 × 304.1
= 5.05 L
Hence, the volume occupied is 5.05 L.
