7.8% CaSO4 by mass means
7.8 g CaSO4/100 g solution.
So in 24 g of the solution, there must be
7.8 x (24/100) = ?? g CaSO4
24.0 g solution - g CaSO4 = grams solvent.
7.8 g CaSO4/100 g solution.
So in 24 g of the solution, there must be
7.8 x (24/100) = ?? g CaSO4
24.0 g solution - g CaSO4 = grams solvent.
