The formula for epsom salt is MgSO4 . 7H20 If 1.250 g of the compound is dissolved in water, calculate the number of milliliters of .200 M Ba(NO3)2 that would be required to precipitate all of the sulfate ions as barium sulfate.
Do it for 1.000 g of alum, which is AlK(SO4)2 .12H2O.

I already did part one. please help me for part 2
