      2) If I dilute 250 mL of 0.10 M lithium acetate solution to a volume of 750 mL, 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).
