A gaseous substance weighing 0.5g occupies volume of 1.12l at new. calculate molar mass of the substance |
|
Answer» "1 mole of any gas at NTP OCCUPIES 22.4 LITRES of VOLUME." so, number of MOLES in 1.12 litres of the gaseous substance = 1.12/22.4 = 0.05 given that, mass of 0.05 moles of the gaseous substance is 0.5 grams Hence, mass of 1 mole of the gaseous substance is 10 grams Therefore the molecular mass of the gaseous substance is 10 grams. Hope it helps!! |
