Question

Derive the relation between molar mass and density?

Answer 1

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

Hey mate there is you answers

Answer 2

Answer:

Vapor density of gas = Molar mass of gas / 2

Explanation:

Vapor density of gas = Density of gas / density of standard gas

standard gas ⇒ hydrogen

Vapor density of gas = Dgas / DH₂    {D ⇒ density}

density = mass / volume

VD of gas = mass of certain volume of gas / mass of some volume of H₂

                 = mass of 22.4L of gas @ STP/ mass of 22.4L of H₂ @ STP

mass of 22.4L of gas @ STP = Molar mass of gas

VD of gas = Molar mass of gas / Molar mass of H₂

VD of gas = Molar mass of gas / 2
