A volume of 3.36 l dry chlorine gas at 0°C and 1 atm was passed over a heated metal when 13.35 g of chloride of the metal was formed. If the atomic mass of the metal is 27, its valency is
Answer:
3.00
Solution:
Moles of = 3.36/22.4 = 0.15, so Cl atoms = 0.3 mol = 10.65 g. Mass of metal = 13.35 - 10.65 = 2.7 g = 2.7/27 = 0.1 mol. Ratio Cl : M = 0.3 : 0.1 = 3 : 1, so the chloride is . Valency = 3. Ans: 3.
