Hi there!
Approximate atomic mass of metal =
6.4 / specific heat = 6.4 / 0.115 = 55.65
In 100 g of metal oxide, weight of metal = 77.28 g
Weight of Oxygen = 22.22 g
w1 / w2 = E1 / E2
Equivalent weight of Oxygen = 8
Equivalent weight of metal = 77.28 / 22.22 × 8
= 27.82
Valency of metal = approximate atomic weight / equivalent weight
= 55.62 / 27.82
= 2
Hence, the valency of metal is 2.
Hope it helps!
