Question

The equivalent weight of an element is 4.Its chloride has v.D. 59.5. Then,the valency of the element is

Answer 1

Answer: Mol.wt chloride MCln = 59.5 × 2 = 119

suppose atomic mass of M = α

α + 35.5n = 119

Eq.mass = At.mass ÷ valency

At.mass = E × n

where n = valency (or) E ×  n + 35.5n = 119

where E = 4 (given)

4n + 35.5n = 119

n = 3.o1
