Question

The vapour density of a chloride of a metal is 81.5 (H=1) and the chloride contains 34.46 % metal. The specific heat of the metal is 0.115 . The molecular formula of chloride is (A) MCl2 (B) M2Cl3 (C) MCl3 (D) MCl4

Tardigrade Admin · Accepted Answer

Vapour density of chloride =81.5 Molecular mass =2 × 81.5=163 Metal weight 34.46 % of Chlorine weight =65.54 % of 163=106.8 Number of chlorine atom =(106.8/3.5)=3 Thus, molecular formula of chloride MCl3.

Q. The vapour density of a chloride of a metal is $81.5 (H = 1)$ and the chloride contains $34.46%$ metal. The specific heat of the metal is $0.115$ . The molecular formula of chloride is

$MC l_{2}$

$M_{2} C l_{3}$

$MC l_{3}$

$MC l_{4}$

Vapour density of chloride $= 81.5$
Molecular mass $= 2 \times 81.5 = 163$
Metal weight $34.46%$ of Chlorine weight $= 65.54%$ of $163 = 106.8$
Number of chlorine atom $= \frac{106.8}{3.5} = 3$
Thus, molecular formula of chloride $MC l_{3} .$
