Question

M
- Assuming the atomic weight of a metal M to be
56. find the empirical formula of its oxide contai.
ning 70.0% of Mo​

Answer 1

Answer:

atomic weight of metal M = 56

in an oxide,  metal is  70% by mass        and so  oxygen is 30% by mass.

let there be  n atoms of  oxygen per 1 atom of metal.

Then  proportion of the masses of metal and oxygen :  

            56 :  n * 16  = 70  : 30

          16 n = 56 * 30 / 70

                n = 24/16 = 1.5

There are two atoms of metal for 3 atoms of Oxygen.:        M2 O3
