The vapour density of a chloride of an element is 39.5. The Ew of the elements is 3.82. The atomic w — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Mwt 2 2 39.5 79 VD x x Eq wt of chloride = eq wt of element + eq wt of chlorine 3.82 35.5 39.32 >>vf of chloride = 79 2 39.32 So valence of element = 2 At wt = 2 3.82 7.64g x 145. What weight of a metal of equivalent weight 12 will give 0.475 g of its chloride? (a) 0.12 g (b) 0.24 g (c) 0.36 g (d) 0.48 g Equivalent weight of metal Equivalent weight of compound Weight of metal Weight of compound 12 Weight of metal 12 35.5 0.475 Weight of metal 0.12g >> >> The correct option is (a) 146. How many grams of phosphoric acid would be needed to neutralise 100 g of m
