Question

a metel has its velocity 2 and oxide molar mass 40 what is that metal​

Answer 1

Answer:

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-2.560

=24g/mol.
