Answer:
The equivalent mass of oxygen is 8 .
The equivalent mass of metal is 16.
If it is a alkaline earth metal, then its molecular mass will be twice its equivalent mass.
It will be 32.
The molecular mass of metal oxide will be 32+16=48
The equivalent mass of metal oxide will be 248=24. It is 1.5 times that of metal.
