Question

What is the density of methane, CH4 in a vessel where the pressure is 910 torr and the temperature is 255 K

Answer 1

Answer: Density of methane is 0.92 g/L

Step-by-step explanation:

The relation between density and molar mass is :

`d=(PM)/(RT)`

where , d = density

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

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

R = gas constant =
`0.0821Latm/Kmol`

T = temperature = 255 K

Putting the values :

`d=(1.20atm* 16g/mol)/(0.0821Latm/Kmol* 255K)=0.92g/L`

Thus density of methane is 0.92 g/L
