Solutions Molarity & Dilutions Practice Available

The site has added unlimited practice problems for two categories of solutions, molarity & dilutions.  You can calculate the molarity of a solution given grams or moles, or calculated the volume, moles or mass of a substance given two of the variables.  Many can me done with just a calculator, but you should download a periodic table (Texas Chemistry STAAR Reference Materials) for the molar masses you will need.

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.
