A volume of 1.12 l dry chlorine gas at 0°C and 1 atm was passed over a heated metal when 5.55 g of chloride of the metal was formed. If the atomic mass of the metal is 40, its valency is
Answer:
2.00
Solution:
Moles of Cl₂ = 1.12/22.4 = 0.05, so Cl atoms = 0.1 mol = 3.55 g. Mass of metal = 5.55 - 3.55 = 2.0 g = 2.0/40 = 0.05 mol. Ratio Cl : M = 0.1 : 0.05 = 2 : 1, so the chloride is MCl₂. Valency = 2. Ans: 2.
