Question

Relationship between molecular mass and density of a gas

Answer 1

Answer:

In general, density of any matter depends on its given mass, not molar mass, IE, independent . Only for gases, 22.4L of any gas at stp is 1 mole. For solids and liquids, no. Of moles= (volume× density)÷ molar mass.

Explanation:

The molar mass of nitrogen is slightly larger than molar volume, so its density is slightly greater than 1 g/L. Alternatively, the molar mass of a gas can be determined if the density of the gas at STP is known.

Vapour density is the density of a vapour in relation to that of hydrogen. It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen. vapour density = mass of n molecules of gas / mass of n molecules of hydrogen.
