14. Birikmaning eng sodda formulasi CₓHᵧ. Formuladagi x/y = 1/2 bo‘lsa, birikmadagi uglerod massasi vodorod massasidan necha marta ko‘p ekanligini aniqlang. Variantlar: 1/2, 2, 6, 3.

Uglerodning nisbiy atom massasi 12, vodorodniki esa 1. Shuning uchun uglerod va vodorod massalarining nisbati:

\(\frac{m(C)}{m(H)}=\frac{12x}{y}=12\cdot\frac{x}{y}=12\cdot\frac{1}{2}=6\).

Javob: 6 marta (3-variant).
