0.5 g of sample of coal used in a bomb calorimeter for the determination of calorific value. The
calorific value of the coal was found to be 8600 cal/g. The ash formed in the bomb calorimeter was
extracted with acid and the acid extract was heated with barium nitrate and a precipitate of barium
sulphate (BaSO4) was obtained. The precipitate was filtered, dried and weighted. The weight of
precipitate was found to be 0.05 g. Calculate the percentage of sulphur in the coal sample.
