Molarity is a unit of _______ 

• concentration

• pressure

• mass

• particles

Take a look at the equation for molarity. If a solution has a HIGH number of moles, what would you expect about its concentration?

• A solution with a  high number of moles of solute would be highly concentrated, since the molarity would be greater.

• A solution with a  high number of moles of solute would not be concentrated, since the molarity would be lower.

• liters

• moles

• molarity
