you weigh out 7.25 grams of NaCl and dissolve this sample in 50 mL of deionized water, and then you put it in an empty volumetric flask weighing 57.221 g. After the whole thing has dissolved, you add water all the way up to the 100.0 mL mark of the volumetric flask (flask and solution together weighs 162.9145 g.) what’s the mass % of NaCl in this solution?
