To solve stoichiometry problems, you must always calculate numbers of moles. Recall that molarity, M, is equal to the concentration in moles per liter M = mol/L Express your answer with the appropriate units mass of AgCl = 23.4 g Submit Hints My Answers Give Up Review Part Correct Significant Figures Feedback: Your answer 23.46 g was either rounded differently or used a different number of significant figures than required for this part.

Explanation / Answer

AgNO3 + KCl ---> AgCl + KNO3

hence potassium chlodire moles = silver nitrate moles

silver nitrate moles = M x V = 0.162x 1= 0.162

KCl moles = 0.162

we were given KCl volume = 3.85 L

hence Molarity of KCl = moles/vol   0.162 /3.85 = 0.042 M
