Molar Gas Volume: Stoichiometry With Gases
We know a lot about ideal gases, including how to use all of the ideal gas laws. But we haven't talked much about how to do stoichiometry with gases. As it happens, we can do stoichiometry with gases not just using molar quantities, but...

Calculating Ion Concentrations in Solution
We know that concentration is typically expressed with molarity, which is moles per liter. But how do we know how many moles of solute are present in solution when an ionic solid dissolves in water? It's not so simple because these will...

Acid-Base Titration
Any introductory chemistry class will include titrations, and to do these, you have to do math. But you get to see pretty colors, too! Here's a quick run through of the stoichiometry of it all.

Practice Problem: Titration Calculations
Titration is a way to do stoichiometry with acids and bases. The equivalence point tells us something about the moles of acid and base that are present in solution at that moment. And if we know one of those values, we can know the...

Practice Problem: Enthalpy of Vaporization
Can we do stoichiometry regarding phase changes? Sure! If we know how many moles of a substance we have, and the energy associated with each mole of that substance undergoing a particular phase change, we can get the energy associated...
Professor Dave Explains
Practice Problem: Density of a Gas
If we can use the ideal gas law to find the molar mass of a gas and therefore identify the gas, what can we do with the density of a gas? Well, pretty much the same thing, it just involves one extra calculation, so let's give it a try!
