Dear Student,

CH4  +  2O2  →  CO2 + 2H2O     ; ∆H=-1665 kJ/mol1 mol of methane gives 1665 kJ/mol of energy
16 g of methane produces 1665 kJ of energySo, 10 kg i
e
 10000g of methane gives 166516×10000=1040625 kJ of energyThat means the 10 kg of gas produces 1040625 kJ of energyEnergy needed per day = 15000 kJSo, 1040625 kJ of energy comes for = 104062515000=69
37Thus, the quota of 10 kg will last for 69 days

a gobar gas plant produces methane and supplies to the family .If family required 15000kj of energy per day how many days will the quota of 10kg will last
