Question

Equal volume of oxygen and second gas weight one and 1.375 gram and the same experimental conditions which is the unknown gas

Answer 1

Explanation:

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 1.375 gm of that gas

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

O2

1

M=1.375

M=76 gm/mol

Of the above gases, CS2

has a molecular mass of 76 gm/mol.

I think you did not provide the options. since I was asked the same question earlier...the answer is CS2
