two elements x of atomic weight = 75 and y of atomic weight =16 combine to give a compound having 75.8 per cent of x . the formula of the compund...is..
Element | Percentage by weight | Atomic weight | Relative no. of atoms | Simple ratio |
X | 75.8 | 75 | 1 | 2 |
Y | 24.2 | 16 | 1.5 | 3 |
Therefore the formula of the compound is X2Y3.
