The practice problems can be found by going to the practice site, http://practice.franzscience.com, the choosing "Unit 12-Solutions" from the drop-down menu. Choose the lesson in which you are interested on the right - then push the button on the right for unlimited practice problems. The topics with practice problems currently available are: Calculating Concentration and Calculating Dilutions.

When complete, the solutions unit will include lessons and practice problems covering ten (10) topics, including such things as the special properties of water, solubility, solubility curves, electrolytes, and colligative properties.

]]>Dilutions calculations are also on-line. They are pretty straight forward. Given the equations M1V1 = M2V2, calculate molarity or volume given the other variables. Right now, all volumes are in liters, so there is no conversion to mL necessary, but that is expected to change in the near future.

Just go to http://practice.franzscience.com/solutions.html.
