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.
