Question

Bivalent metal has the equivalent weight 12.Molecular weight of its oxide

Answer 1

Answer:

40

Explanation:

Molecular wt.=equivalent wt.×n-factor

n-factor of the metal ion is 2 so molecular wt. is 24

since it is a bivalent ion it requires only one oxygen atom combine to form oxide therefore the molecular wt. of the oxide is

Molecular wt.=molecular wt. of metal + molecular wt. of oxygen

i.e., Molecular wt.=24+16=40
