Sample of coal containing 80% C, 15% H and 5% ash is tested in Bomb calorimeter. The following results were obtained. Weight of the coal burnt = 0.98g, Weight of water taken = 1000g, water equivalent of bomb = 2500g, Rise in temperature = 2.5C

Assuming the latent heat of steam as 580 cal/g. Calculate the lower calorific value of the fuel in cal/g. (Write the answer rounded off to whole

number without any
