If you have 200 mL of a 60% sodium chloride solution, how much NaCl is dissolved in the solution?

A 120 g

A 60% NaCl solution would be made by dissolving 60 g of NaCl in slightly less than 100 mL of water, and then increasing the volume of the solution to the final 100mL of water. If we had 200 mL of a 60% NaCl solution, then there would be 120 g of NaCl dissolved in the solution.
