Mixture X decolorizes bromine water, indicating the presence of unsaturation, and upon treatment, it forms mixture Y through disproportionation, which does not decolorize bromine water. The hydrogenation of both mixtures leads to a hydrocarbon Z with a specific mass fraction of hydrogen. The goal is to determine the total number of hydrogen atoms in the two liquids of mixture X based on the chemical behavior described."}
