The sixth member of the class of the aliphatic alkanes is Hexane with the molecular formular C6H14
Percentage by mass of Hydrogen = massofHydrogenincompoundTotalmassofcompound×100
Total mass of compound, C6H14 = (12 x 6) + (1 x14) = 72 + 14 = 86
Mass of Hydrogen in compound = 14(H) = 14×1 = 14
% mass of H = 1486×100
= 16.28%
