C5H10

M=5×12+10=70

70gC5H10......5×12 C..............10 H
100.......................p1.......................p2

[tex]p1 = \frac{5 \times 12 \times 100}{70} = 85.71\% \: carbon[/tex]

[tex]p2 = \frac{10 \times 100}{70} = 14.28 \% \: hidrogen[/tex]

CH3-C(CH3)=CH-CH3      C5H10
%C = 5·12·100/70 = 85,714%      %H = 10·1·100/70 = 14,285%
