Question #63208

Chapter 11

Liquid butane (C4H10) and liquid propane (C3H8) are often stored in cylinders, to be used as fuels. The normal boiling point of butane is −0.5 ∘C and its ΔHvap is 23.1 kJ/mol. The corresponding values for propane are −42.1 ∘C and 15.4 kJ/mol, respectively.

1)How much energy is required to vaporize 135 g of butane at its boiling point? The heat of vaporization for butane is 23.1 kJ/mol.

2)What volume will 135 g of butane occupy at 745 torr and 35 ∘C?
