Hello,

There's this one problem I'm having quite a lot of trouble with.

I know that to solve it, you have to find out the 'amount' (coefficients) of each compound in the mixture, but I honestly have no clue on how to do that.

The question goes as follows:

There's a mixture containing K2S, K2SO3 and K2SO4 (unequal amounts of each compound)

The m% of K is 60,0%

How much O is present in this mixture?

Any help would be greatly appreciated, thanks
