A metal M of equivalent mass E forms an oxide of molecular formula `M_(x)O_(y)`. The atomic mass of the metal is given by the correct equation.A. 2E(y/x)B. xy/EC. E/yD. E/2(x/y)

Answer» Correct Answer - A
If m is the atomic mass of the metal M, then 16y g of oxygen combine with xm g of the metal
`:.` 8 g of oxygen will combine with metal
`= (xm)/(16y)xx8 = (xm)/(2y)`
`:. (xm)/(2y)=E`
or `m=2E//(y//x)`
