What is the concentration of sodium chloride in the final solution if...?
What is the concentration of sodium chloride in the final solution if 25.34 mL of 0.113 M BaCl2 completely reacts and the total volume of the reaction is 110.4 mL, given the reaction BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2NaCl(aq)

Moles BaCl2 = 0.113 mol/L X 0.02534 L = 2.86X10^-3 mol BaCl2
Moles NaCl = 2.86 X 10^-3 mol BaCl2 X (2 mol NaCl/1 mol BaCl2) = 5.73 X 10^-3 mol NaCl
Concentration NaCl = 5.73X10^-3 mol / 0.1104 L = 0.0519 mol/L NaCl
