WebIf the air pressure and temperature are known then the exact number of moles of gas can be calculated using the formula: PV = nRT. Example: Calculate the number of moles of gas produced when 50 cm 3 of gas are collected in a gas syringe at 25ºC and 1 atmosphere (100.0 kPa) pressure. PV = nRT. 100.0 x 0.05 = n x 8.314 x 298. remove and install windows
