Calculate the weight of sulphur present in 1.5 moles of hydrogen sulphide.
Hydrogen sulphide gas burns in oxygen to yield 12.8 g of sulphur dioxide gas as under: 2H2S + 3O2 → 2H2O + 2SO2 (i). calculate the volume of hydrogen suulphide at STP. Also, (ii). calculate the volume of oxygen required at STP. Which will complete the combustion of hydrogen sulphide determined in litres.
