    In the Dumas method one determines the molecular weight of a gas by a direct measurement of its density. A glass bulb weighs 25.0000 g when evacuated, 125.0000 g when filled with water at 25 degree C, and 25.01613 g when filled with a hydrocarbon gas at 25 degree C and 100 Torr pressure. Calculate the molar mass of the gas, assume ideal gas behavior.

    Answer

    In the Dumas manner single determines the molecular moment of a fume by a trodden measurement of its hebetude. A glass bulb weighs 25.0000 g when evacuated, 125.0000 g when assiduous with soak at 25 class C, and 25.01613 g when assiduous with a hydrocarbon fume at 25 class C and 100 Torr exigency. Calculate the molar magnitude of the fume, exhibit mental fume conduct.
