a) C₄H₁₀:

$\frac{{\text{m}}_{\mathrm{C}}}{{\text{m}}_{\mathrm{H}}}=\frac{4\cdot 12\mathrm{u}}{10\cdot 1\mathrm{u}}=\frac{48\mathrm{u}}{10\mathrm{u}}=\frac{24}{5}$

Więc:

${\text{m}}_{\mathrm{C}}:{\text{m}}_{\mathrm{H}}=24:5$

 

b) C₄H₈:

$\frac{{\text{m}}_{\mathrm{C}}}{{\text{m}}_{\mathrm{H}}}=\frac{4\cdot 12\mathrm{u}}{8\cdot 1\mathrm{u}}=\frac{48\mathrm{u}}{8\mathrm{u}}=\frac{6}{1}$

Więc:

${\text{m}}_{\mathrm{C}}:{\text{m}}_{\mathrm{H}}=6:1$

 

c) C₄H₆:

$\frac{{\text{m}}_{\mathrm{C}}}{{\text{m}}_{\mathrm{H}}}=\frac{4\cdot 12\mathrm{u}}{6\cdot 1\mathrm{u}}=\frac{48\mathrm{u}}{6\mathrm{u}}=\frac{8}{1}$

Więc:

${\text{m}}_{\mathrm{C}}:{\text{m}}_{\mathrm{H}}=8:1$
