Question

The density of a gas is 2.5g/L at 127°C and 1 atm. The molecular weight of the gas is​

Answer 1

Answer:

$M= 3.325 \times 10^{-2} kg/m^3$

Explanation:

density = $\frac{PM}{RT}$

where P - pressure of the gas

 M- molecular weight of the gas

T - temperature of gas

by putting all values

Density = $\frac{1 \times 10^5 \times M}{8.314 \times 400}$ = $1 kg/m^3$

$M= 3.325 \times 10^{-2} kg/m^3$
