The molar entalpy if butane is :

22.44kJ / mol

The molecular formula = C₄H₁₀

molar mass = 12 × 4 + 1 × 10 = 58g/mol

Moles in 14kg:

14 × 1000= 14000g

Moles = 14000 ÷ 58 = 241.379 moles.

1 mole = 22.44 kj

241.379 moles = ?

241.379 × 22.44 = 5416.54 kJ

The family uses : 10000 / 1000 = 10 kJ per day

5416.54 / 10 = 541.654 days.
