Question

How many grams of silver will be displaced from a solution of AgNO₃ by 4 g of magnesium?

(a) 18 g

(b)  4 g

(c) 36 g

(d) 16 g

Answer 1

Correct option (c) 36 g

Explanation:

Weight of magnesium = 4 g

We know that,  Weight of silver displaced (M)/Weight of magnesium

= Equivalent weight of silver/ Equivalent weight of magnesium

or M/4 = 108/12

or M = 108 x 4 /12 = 36 g
