Concentration

In order to dilute a solution, you need to

• add more of the solid

• add more water

• find the mass

• find the volume

The amount of solute actually dissolved in a given amount of solvent.

• dilution

• concentration

• saturated solution

• supersaturated mixture

When a solvent contains as much of the solute as it can hold, the solution is said to be

• supersaturated

• diluted

• saturated

• unsaturated

How does a solution become supersaturated?

• dissolve lots of solute in it.

• dissolve a little solute in it. 

• dissolve more solute than you should be able to. 

• dissolve a super amount of solvent in it. 

Which is an example of a solute?

• Egg whites

• Sugar

• Water

• Acetone

What does it mean to dilute a solution?

• lower the concentration of solute per solvent

• increase the concentration of solute per solvent

You can make a solution more concentrated by adding __________.

• solute

• solvent

• water

What is the concentration of a solution if 5 grams of salt is dissolved in 100 mL of water?

• 0.05 g/mL

• 0.5 g/mL

• 5 g/mL

• 50 g/mL

Which of the following factors does NOT affect the concentration of a solution?

• Temperature

• Amount of solute

• Volume of solvent

• Color of the solution

If a solution has a concentration of 2 M, what does 'M' stand for?

• Moles per liter

• Mass per liter

• Molecules per liter

• Milliliters per liter
