Stoichiometry Expanded

We first turned in our solubility labs from Friday. When then began our discussion, extending off the solubility problems. (Also we have a test on friday) Everything was mostly a review from stoichiometry 1st semester except for molarity and molality.

When then preceded to solve this problem for practice:

How much calcium carbonate will be precipitated by adding 25.0 ml of calcium chloride to 25.0ml of 56 M potassium?



I left out the ml to l conversation factor and the 1 to 1 mole conversation for the second equation above.

We also did the first problem of the worksheet.




Remember to keep doing those web assigns and worksheets for preparation for the test on friday!
The next scribe will be Ben T !
