What is a solvent?

• The substance that does the dissolving in a solution.
• The substance that is being dissolved in a solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons

Molarity is measured in

• mols per kg

• mols per L

• mols per kJ

• mols per mL

• grams per mL

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. 

when the solvent cannot dissolve any more solute

• supersaturated

• saturated

• volume

• mass

• unsaturated

When you make a dilution, which of these values remains constant?

• The molarity (M)

• The total moles of solute

• The volume (V)

• The concentration

As we dilute a solution.....

• The volume increases and the molarity (M) increases

• The volume increases and the molarity (M) decreases

• The volume decreases and the molarity (M) increases

• The volume decreases and the molarity (M) decreases

How many mL of stock solution of 2.0 M NaCl do you need to prepare 100. mL of 0.150M NaCl?

• 7.5 mL

• 15 mL

• 1333 mL

• 200 mL

Calculate the Molarity in a solution containing 40.0 g of NaCl dissolved in 500.0 ml of H2O.

• 0.08 M

• 12.5 M

• 1.37 M

• 0.74 M
