The formula of water is H2O. The gram atomic mass of hydrogen is 1.008 and the gram atomic mass of oxygen is 15.999. Therefore, the mass percent composition of hydrogen in water is 100{(2)(1.008)/[(2)(1.008) + 15.999] or 11.19 %.The percent composition of hydrogen in water is: 11,19 %.
The percent composition of calcium hydrogen carbonate is:- calcium: 24,691 %- hydrogen: 1,235 %- carbon: 14,814 %- oxygen: 59,259 %
hydrogen and helium
