To calculate the molar concentration of the ammonium thiocyanate solution, we can use the concept of stoichiometry and the fact that the reaction between silver nitrate (AgNO₃) and ammonium thiocyanate (NH₄SCN) is a 1:1 molar ratio.The balanced chemical equation for the reaction is: Given:- Volume of silver nitrate solution ( ) = 8.50 mL- Molarity of silver nitrate solution ( ) = 0.05120 mol/L- Volume of ammonium thiocyanate solution ( ) = 10.00 mLFirst, calculate the number of moles of silver nitrate used in the titration: Since the reaction is a 1:1 molar ratio, the moles of ammonium thiocyanate will be the same as the moles of silver nitrate: Now, calculate the molar concentration of the ammonium thiocyanate solution: Therefore, the molar concentration of the ammonium thiocyanate solution is .
