Question

Equal volumes of oxygen gas and second gas weigh 1 and19/8 gm resp find gas

Answer 1

Answer:

Since, the gases occupy same volumes at same experimental conditions, this means that

Moles of Oxygen present in 1.0 gm of Oxygen gas = Moles of Gas present 2.375 gm of that gas

Let the molecular mass of the unkonwn gas be M gm/mol

⟹ 1/32

= 2.375/M

⟹M=76 gm/mol

Of the above gases, CS sq

has a molecular mass of 76 gm/mol.
