In 24 g of a 7.8% by mass solution of CaSO4? How many grams of solute are present gCaSO4? how many grams of solvent are present g solvent?

  • chemistry -

    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.
