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
