Answer:
This is the answer
Explanation:
ANSWERANSWER
100 g of metal oxide will contain 40 g oxygen and 60 g metal.
Number of moles of oxygen
16g/mol
40g
=2.5mol
The valency of metal is 2. The formula of metal oxide will be MO.
Hence, number of moles of metal = number of moles of oxygen =2.5mol
The atomic weight of the metal is-
2.5
60
=24g/mol.
So, the correct option is A
