Dilutions Practice

The term molar, which describes a solution's concentration, is written as?

• M

• mol

• g

• g/L

A dilution is when

• solute is added to the volume of stock solution

• water is added to the volume of stock solution

• solute is removed from the volume of stock solution

• water is removed from the volume of stock solution

Molarity is ...

• grams of solute/deciliters of solvent.

• grams of solute/liters of solution.

• moles of solute/liters of solution.

• moles of solute/milliliters of solvent.

What is a concentrated solution?

• a solution that has a large amount of solute in a large volume of solvent

• a solution that has an equal amount of solute in the same volume of solvent

• a solution that has a small amount of solute in a large volume of solvent

• a solution that has a large amount of solute in a small volume of solvent
