How many grams of BaSO4 can dissolve in 1.5 L of a 0.010 M solution of Na2SO4?

Ksp= 1.1 x 10^-10

I thought the answer was 1.1x10^-8 M then multiply by the molar mass to get the amount of grams but my answer isn't correct. PLEASE HELP!

  1. You are right, you just stopped too soon./
    (BaSO4) = (Ba^+2) = 1.1E-10.0.01 = ?? moles/L.
    Now multiply 1.5 L (the step you omitted), THEN multiply by molar mass BaSO4 to convert to grams.
