An LPG cylinder contains 14 kg of butane. A family requires `2xx10^(4)kJ` of heat for their cooking purpose everyday. By how many days will the butane in the cylinder be used up (Given: heat of combustion for butane=`-2658kJ*mol^(-1)`)-

a. A cylinder of gas is assumed to contain 11.2 kg of butane. If a normal family needs 20000kJ of energy per day for cooking, how long will the cylinder last? Given that the heat of combustion of butane is 2658 kJ mol^(-1) .

A cylinder of indane gas contains 11.2 kg of butane.A normal family requires 25000 kJ energy per day for cooking.How long will the cylinder of gas last if the efficiency of combustion is 80%? (Heat of combustion of butane is 2658 kJ mol^(-1) ).

a. A cylinder of gas is assumed to contain 11.2 kg of butane. If a normal family needs 20000kJ of energy per day for cooking, how long will the cylinder last? Given that the heat of combustion of butane is 2658 kJ mol^(-1) . b. If the air supply of the burner is insufficient (i.e. you have a yellow instead of a blue flame), a portion of the gas escape without combustion. Assuming that 33% of the gas is wasted due to this inefficiency, how long would the cylinder last?

A cylinder of cooking gas contains 14.0 kg of butane. If a family needs 20,000kJ of energy per day for cooking, how long will the cylinder last? The enthalpy of combustion of butane is -2658 kJ mol^-1

A cylinder of gas is assumed to contain 11.6 kg of butane (C_4H_10) . If a normal family needs 20000kJ of energy per day, then the cylinder will last for : (Given that ΔH for combustion of butane is – 2658kJ)
