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.

From ideal gas equation we know that: -

PV = nRT


⇒ PV = m/M x RT


Where, P = pressure = 1 bar


R = universal gas constant = 0.083 bar dm3 K–1 mol–1


T= temperature = 31.1 +273 = 304.1 K


m = mass of CO2 = 8.8 g


M = molar mass CO2 = 44g


Let the volume be V


∴



= 5.05L


∴ The volume occupied is 5.05 L.
