A student carries out an experiment to produce a precipitate of silver chloride, AgCl\text{AgCl}AgCl, using the following reaction:
MgCl2(aq)+2AgNO3(aq)→2AgCl(s)+Mg(NO3)2(aq) \text{MgCl}_2(\text{aq}) + 2\text{AgNO}_3(\text{aq}) \rightarrow 2\text{AgCl}(\text{s}) + \text{Mg(NO}_3)_2(\text{aq}) MgCl2(aq)+2AgNO3(aq)→2AgCl(s)+Mg(NO3)2(aq)They find that 10.0 cm3 of 0.15 mol/dm3 MgCl2\text{MgCl}_2MgCl2 solution reacts exactly with 12.0 cm3 of AgNO3\text{AgNO}_3AgNO3 solution.
Calculate the concentration, in mol/dm3\text{mol/dm}^3mol/dm3, of the AgNO3\text{AgNO}_3AgNO3 solution.
