Practice Problem: Dilution Calculations
Dilution calculations are easy! We just need to know about the concept of concentration, and then the equation M1V1 = M2V2. Try some examples!
Professor Dave Explains
Practice Problem: Molarity Calculations
Solution concentration is measured in molarity, which is moles solute per liter of solution. Can we calculate concentration, moles, or volume, given the other two values? Sure, it's easy!

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.

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...

Expressing Concentration by Mass Percent
We know how to express solution concentration in terms of molarity and molality, but the common public also needs to communicate concentration for certain reasons, and they don't really know about moles and things like that. What do they...
