Chemical Composition 4

Tomorrow in class, we will be participating in the Formula of a Hydrate Lab if we answer the pre-lab questions correctly. One of the questions will be about the procedure, and the other one will be a unit conversion question. I am confident that I will answer both questions correctly because I am aware of how to answer conversion questions and I have read over the procedure multiple times.

The other day in class, we learned how to convert between moles in a balanced chemical equation, mass in grams, representative particles (atoms, molecules, formula units, ions), and the volume gasses at STP. We were given the "Mole Road Map" to help with this, which can be seen below:

I think I am speaking for the majority of the class when I say that the Chemical Composition exam was one of the hardest we have taken this year. It was stressful and not very many people finished before the bell rang. Some of us still may have trouble, so I have found a video and a website that can help people if they so wish.

We have been learning all kinds of uses for dimensional analysis, such as converting elements as well as compounds.
