Butane (C4H10 ), is commonly used as cooking gas. Assume butane is an ideal
gas, calculate the pressure of 12kg (12,000g), of butane in a gas cylinder of
volume 30dm3 given that the temperature of the room is 25°C
[Take molar gas constant R = 0.0821dm3
atm K-1mol-1
, C = 12, H = 1,
mole = mass/molar mass]
