Question

the heat of combustion of ethane gas is 373 kcal per mole. Assuming that 50% of heat is lost, how many liters of ethane measured at STP must burnt to convert 50 g of water at 10° C to steam at 100° C? One mole of gas occupies 22.4 liters at STP. Take latent heat of steam = 2.25 × 10⁶ J/g⁻¹.

Answer 1

Answer:

As, 50% of heat is lost, ∴ total heat produced =2×31.29×106cal. Heat of combustion =373×103cal/mole .
