100

_____________ is the amount of solute that can dissolve in a given amount of solvent at a given temperature

What is solubility?

100

The solution concentration expressed in terms of molarity

mol/L

100
When diluting a solution this does not change
What is the number of moles
100

This determines the polarity of a molecule

200

This does NOT change when a solution is diluted by the addition of solvent.

What is the number of moles of solute?

200
A solution in which a small amount of solid still remains at the bottom of the solution
What is a saturated solution
200

If we were looking to find the amount of moles given the molarity and volume, what is the equation we could use?

What is mol= L x M
