In the Table of Chemicals in the Example Pre-lab Notebook in the Laboratory Manual, the moles of water are not calculated. Why?

In this reaction, water is not involved in the chemical reaction and thus it is not necessary to calculate the moles of water.

Upon beginning your experiment, you notice that your round-bottomed flask has a small "star" crack in it. Your safest option is to...

Notify your TA and replace it immediately with new glassware.
