Answer: Density of methane is 0.92 g/L

Explanation:

The relation between density and molar mass is :

[tex]d=\frac{PM}{RT}[/tex]

where , d = density

P = pressure = 910 torr = 1.20 atm     (760 torr=1atm)

M = molar mass = 16 g/mol ( for methane)

R = gas constant  = [tex]0.0821Latm/Kmol[/tex]

T = temperature = 255 K

Putting the values :

[tex]d=\frac{1.20atm\times 16g/mol}{0.0821Latm/Kmol\times 255K}=0.92g/L[/tex]

Thus density of methane is 0.92 g/L
