Question

1.40dm³ volume of gas measure at temperature of 27 degree C and pressure of 900 torr was found to have a mass of gas 2.27gm .Calculate Molecular mass​

Answer 1

Explanation:

by ideal gass equation :pv=nRT

n=wt/gmw

pv=wt/gmw

PM=m/VRT

M=mRT/VP

1torr=62.93mmHg

2.27

$2.27 \times 62.93 \times 300 \div 1.40 \times 900$

340.121
