Unformatted text preview: what will the concentration of this solution be? 0.033 M (the final volume is 750 mL, set up the equation from that. Note that the phrasing difference between problems 1 and 2 makes a big difference in the final answer). 3) If I leave 750 mL of 0.50 M sodium chloride solution uncovered on a windowsill and 150 mL of the solvent evaporates, what will the new concentration of the sodium chloride solution be? 0.63 M (this is the opposite of a dilutions problem the V 2 value is smaller than V 1 , but otherwise the equation is no different.) 4) To what volume would I need to add water to the evaporated solution in problem 3 to get a solution with a concentration of 0.25 M? 1500 mL 2004 Cavalcade Publishing, All Rights Reserved For chemistry help, visit www.chemfiesta.com Home...
