The solubility of NaCl in water is 35.7 g NaCl/100 g H2O. Suppose that you have 500.0 g of NaCl. What is the minimum volume of water you would need to dissolve it all? The density of water is 1.0 g/mL.
100 grams H2O x (500/37.5) = about 1330 mL. Or look at it this way.
37.5 g NaCl/100 mL = 0.375 g NaCl/1 mL.
So (0.375 g NaCl/mL) x ??mL = 500 g
Solve for ??mL.
