What is the molarity of a saturated solution of potassium sulfate (K2SO4) if the solubility is 13 g per 100 g H2O at 25 oC? The density of the solution is 1.1g/mL

PLEASE SHOW HOW YOU GOT THE SOLUTION, THANKS!

Molarity = moles/liter and the molar mass of pot. sulf. is 174.259 gms/mole.  You have 13 grms in 100 gms water which is = 13 gms/100 mls water = 13/174.259 moles/100mls
= 0.075 moles/100mls = 0.75 moles/liter = 0.75 M.
