Question

3.7 g of a gas at 25°c occupied the same volume as 0.184gr of hydrogen at 17°c and at the same pressure what is the molecular mass of the gas​

Answer 1

Answer:

According to ideal gas equation,

PV=nRT

P and V are the same.

So, n1T1=nT2

or M1w1=M2w2T2

or M13.7×298=20.184×290

M1=41.33g

Molecular mass no is 41.

Answer 2

Answer:

the molecular mass number is 41
