7.5: Solution Stoichiometry - Chemistry LibreTexts

Because these reactions occur in aqueous solution, we can use the concept of molarity to directly calculate the nuer of moles of products that will be formed, and hence the mass of precipitates. In the reaction shown above, if we mixed 123 mL of a 1.00 M solution of NaCl with 72.5 mL of a 2.71 M solution of AgNO 3 , we could calculate the moles (and hence, the mass) of AgCl that will be
