Mixture X, which decolorizes bromine water, undergoes disproportionation to form mixture Y, which does not decolorize bromine water. Both mixtures, when hydrogenated under severe conditions, yield a hydrocarbon Z with a known mass fraction of hydrogen. The goal is to calculate the total number of hydrogen atoms in the two liquids of mixture X based on the stoichiometry of the reactions and the properties of the resulting hydrocarbon."}
