What is molarity?

Back

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution (moles/liters).

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.

If I have 340.0 mL of a 0.500 M NaBr solution, what will the concentration be if I add 560.0 mL more water?

Back

.188 M

Front

True or False? The higher the concentration of a solution, the less solutes it has in it.

Back

False

Which solution is the most concentrated: 1M, 3M, 3.1M, or 2.5M?

Back

3.1M

Front

What happens to the molarity of a solution when you dilute it?

Back

The molarity decreases as the volume of solvent increases.

Front

What is dilution?

Back

Dilution is the process of reducing the concentration of a solute in a solution, usually by adding more solvent.
