Write and balance the equation.
Convert g CaCl2 to mols
Convert g Na2SO4 to mols.
Use the coefficients in the balanced equation to convert mols CaCl2 to mols CaSO4.
Do the same for mols Na2SO4 to mols CaSO4.
The SMALLER value is the correct value to choose for the mols CaSO4 produced and the reagent producing that value is the limiting regent.
