The reaction described in Part A required 3.65 L of magnesium chloride. What is the concentration of this magnesium chloride solution? Express your answer with the appropriate units.
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.
When solutions of silver nitrate and magnesium chloride are mixed, silver chloride precipitates out of solution according to the equation
2AgNO3(aq) + MgCl2(aq) → 2AgCl(s) + Mg(NO3)2(aq)
