A 22.0 mLmL sample of a 1.16 MM potassium sulfate solution is mixed with 14.8 mLmL of a 0.860 MM barium nitrate solution and this precipitation reaction occurs: K2SO4(aq)+Ba(NO3)2(aq)→BaSO4(s)+2KN O3(aq)K2SO4(aq)+Ba(NO3)2(aq)→BaSO4( s)+2KNO3(aq) The solid BaSO4BaSO4 is collected, dried, and found to have a mass of 2.57 gg . Determine the limiting reactant, the theoretical yield, and the percent yield.
