Let's say the mass of the compound is x. By mass, it contains 4 % oxygen. The atomic mass of oxygen is 16g.
Let there be 100g compond in which there is 4 g oxygen.
(To take the minimum mass, assume that there is 1 oxygen atom in it )
But, actually it's 16 g not 4 g.
So, using unitary method,
If 4 g of oxygen = 100g of compound
16g of oxygen = x gram of compound.
Solving for x:
X= 100*16/4 = 400
Hence, the mass of compound is 400g.
