1.	34.05 mL of phosphorus vapour weighs 0.0625 g at 546°C and 0.1 bar pressure. What is the molar mass of phosphorus ?
Answer» ven,Initial pressure, = 0.1Volume, = 34.05 mlVolume, = ?Final TEMPERATURE, = 546°CInitial temperature, = 273°CVolume and 1 bar of pressure = Weight of 1.135 ml of VAPOUR at and 1 bar of pressure = 0.065 g Molar mass, M = 1250 g
