Stoichiometry Returns



Today in 7th period chem we did some stoichiometry with solutions.
That was one problem that we did. Basically you can use mole ratios from a balanced equation, molar masses, and now you can use the molarities to get what you want.

Now we know the mole ratio is related in several ways:

-PV=nRT
-molar mass
-M=moles/L

We can use stoichiometry for pure substances, gases, and now solutions.

If anyone is still having trouble, I would recommend going through the notes from last semester on Stoichiometry, or watch this video:
