17.4 g of K2SO4 contain in 200 ml of the solution. Calculate the molar salt concentration in the solution.

Please check the decision
c=m/(M*ν)=17,4/(174*0,2)=5 mol/L

Molecular weight of K2SO4 is 174 ....

so if 174 dissolved to make 1 liter , that would be a molarity of 1.

We are told 200ml contains 17.4 gm , so 1 liter will contain 87 gm

which is 0.5 mol/liter
