• All of the above

If you use a scale to help you find out which solution is most concentrated, which thing MUST be done?

• add equal amounts of solute to each cup

• add equal amounts of solvent to each cup

• use an equal volume of each solution

• put the cups in the holes first

What is a solute?

• the solid part of a solution

• the liquid part of a solution

• when you add more water to a solution

• when you add more powder to a solution

• a mixture in which a solute dissolves into a liquid
