Calculate the solubility of Ag2CrO4 in grams/100mL of water?

Question

(Ksp = 1.12x10^-12 )

I know how to calcuate the molar solubility, and I know how to convert it into grams/L...but I'm stuck on how to make it grams/100mL

Any Help would be awesome! =D thx!

Answer 1

convert the moles to grams, and then for volume, assume denstiy is the same as water (accurate for dilute solutions)
