Balanced equation: 
<span>CaSO4(aq) + AgNO3(aq) -> Ag2SO4(s) + Ca(NO3)2(aq) 

</span>Twice the amount of silver is needed than SO4 in order to precipitate. Silver would be the limiting reagent (from AgNO3). 
Find the leftover concentration of CaSO4 by subtracting  the amount that reacted with the silver. 
<span>
∴[CaSO4]=[Ca^2+]=0.0500M-0.0390M= 0.0110 M </span>
