Question

A gaseous mixture of H2 and N2O gas contains 66 mass %of N2O WHAT IS THE AVERAGE MOLECULAR MASS OF MIXTURE

Answer 1

This is the answer to your question...i hope it helps you...

Answer 2

Answer:Average molecular weight of the mixture is 29.72 g/mol.

Explanation:

Mass % of$N_2O$ gas = 66% = 0.66

Mass % of $H_2$  gas =  100% - 66%=34 % = 0.34

Molecular weight of $N_2O$ = 44 g/mol

Molecular weight of $H_2$ = 2 g/mol

Average molecular weight of the mixture :

$=0.66\times 44 g/mol+0.34\times 2 g/mol=29.72 g/mol$
