A 75.0 sample of 1.50×10^−2 Na2SO4 is added to 75.0 mL of 1.26×10−2 Ca(NO3)2. What is the % Ca undissolved

Na2SO4 + Ca(NO3)2 ==> CaSO4(s) +2NaNO3

millimols Na2SO4 = mL x M = 1.125
millimols Ca(NO3)2 = 0.945.
I don't know what % Ca undissolved means? and % of what?
It will form 0.000945 mols CaSO4 solid
