# Weight percent concentration calculation with partition coefficients

1. The problem statement, all variables and given/known data
what is the weight percent concentration of SO2 in the exsolved aqueous fluid phase that existed with solution if sulphur has ppm by weight of 90. partition coefficient= 47

2. Relevant equations

partition coefficient- 47= concentration of aqueous fluid/ concentration of solution

3. The attempt at a solution
weight % of sulphur= 32/32+2(16)= 0.5
weight % of oxygen= 0.5
90 ppmw sulphur, since there is 1 mole of sulphur and 2 of oxygen there is 180 ppmw oxygen. for a total of 270 ppmw SO2.
47= 270ppmw/x
x= 270/47
x= 5.74

im not really sure if this is correct, if it isnt could someone point me in the right direction?
