Question

Calculate the density of so2 in g/dm3 at 25°c and 300 torr pressure

Answer 1

Answer:

The density of the sulfur dioxide gas is $1.033 g/dm^3$.

Explanation:

Pressure of the gas = 300 torr =0.394 atm (1 torr = 0.0013 atm)

Temperature of the gas = 25°C = 298 K

PV=nRT (Ideal gas)

$PV=\frac{M}{64.07 g/mol}RT$

$\frac{P\times 64.07 g/mol}{RT}=\frac{M}{V}=Density$

$Density=\frac{0.394 atm\times 64.07 g/mol}{0.0820 atm L/mol K\times 298 K}=1.033 g/L=1.033 g/dm^3$

$1L =1 dm^3$

The density of the sulfur dioxide gas is $1.033 g/dm^3$.
