Answer:
Yes it is possible for chemist to know
Explanation:
The solution is based on the principle that each product or mixture of K2O or K2O2 will have different proportion of K and this would be the differentiating factor.
For example, percentage of K in K2O is 83 while the percentage of K in K2O2 is 71.
Now if the chemist can measure how much K is there in the mixture, then he can use this data to compare with the percentages stated above.
For example, if K has 83 percentage in mixture, it means it is K2O
