Answer:
100 g of metal nitride will contain 28 g of nitrogen and 100−28=72 g of metal.
The atomic mass of nitrogen is 14 g/mol.
28 g of nitrogen corresponds to 1428=2 moles.
The formula of metal nitride is M3N2.
2 moles of N atoms corresponds to 3 moles of metal.
Hence, 72 g of metal is equal to 3 moles.
The atomic weight of metal is 372=24g/mol.
