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 [Select ] Next, to find the the number of moles of Naci he needed, Johnny simply multiplied the [Select] by the volume of water, in liters, which was [Select) L. Then, he calculated the number of grams of NaCl he needed taking this number of...
