QUESTION 21 I1 22 mL of 0 137M MgCin is needed to completely react 15 ml of AgNO3 solution, what is the molarity of AGNO3? Hint First balance the double displacement reaction between MgCl2 (aq) and AGNO3 (aq). Then calculate the number of moies of magnesium chloride Then convert that to moles of silver nitrate Then work out the concentration of silver nitrate Do each step separately instead of all in one line to check that you definitely understand the meaning of each step instead of a process of just units cancelling The Molanty unit symbol is M
