Johnny wished to create a 0.300 M NaCl solution. Johnny only had 50.0 mL of water, however. To create his goal solution, Johnny knew he needed to know the molar mass of NaCl, which was . Next, to find the the number of moles of NaCl he needed, Johnny simply multiplied the by the volume of water, in liters, which was L. Then, he calculated the number of grams of NaCl he needed taking this number of moles of NaCl and the molar mass. Finally, he weighed out this number of grams of NaCl and dissolved the salt in to create the 0.300 M solution.
