Two oxides of a metal contain 27.6% and 30% of oxygen respectively. If the formula of the first oxide is MO, find that of the second?
Now my problem is how to find the atoms of O from the masses of 27.6% and 30.0 %?
The Attempt at a Solution
I can see that in MO, there is one atom of O in the first oxide, So 27.6 = 1 oxygen atom?
