Question

3.6 g of a gas at 27°C occupied the same volume

as 0.2 g of

H2

gas at 127°C and at the same

pressure. What is the molar mass of gas?​

Answer 1

Answer:

Explanation:

Ideal gas Eq

PV = nRT

since P and V are constt

n1/T1 = n2/T2 = PV/R

n1/300 =  (0.2/2)/400

n1/300 = 1/4000

n1 = 3/40  = 3.6/M

M =  3.6 * 40/3  = 48g/mol
