A cylinder of gas is assumed to contain 11.2 kg of butane . If a normal family needs 20000 kJ of energy per day. The cylinder will last (Given that ∆H for combustion of butane is -2658 kJ)
View answer and explanation
Correct option: C
26 days
Option C (26 days) is correct. It is calculated by determining the total energy available from the butane and dividing it by the daily energy requirement.
