Question

Is molar volume of CH4 different from that of NH3?Explain​

Answer 1

The molar volume of CH4 and NH3 gases are the same at STP due to Avogadro's law. Both will occupy 22.4 liters per mole at STP, although they have different molecular weights.

Step-by-step explanation:

The molar volume of a gas at standard temperature and pressure (STP) is the volume one mole of the gas occupies under these conditions. According to Avogadro's law, equal volumes of all gases at the same temperature and pressure contain the same number of molecules. Therefore, at STP, one mole of CH4 (methane) and one mole of NH3 (ammonia) will occupy the same volume. For example, both will occupy 22.4 liters at STP. The difference between CH4 and NH3 is not in their molar volumes but in their molecular weights and structures. While CH4 has a molar mass of approximately 16.0 g/mol, NH3 has a molar mass of 17.0 g/mol.

Answer 2

Step-by-step explanation:

Well At 0 °C and 1 atm pressure (STP conditions), ideal gases have a molar volume of 22.4 Liters. When the molar volumes of NH3 and CH4 are measured at STP, the molar volume of NH3 is 22.1 L and the molar volume of CH4 is 22.4 L. ... NH3 molecules take up more volume than CH4 molecules.
