Concentration

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.

Molarity is measured in

• moles per kg
• mols per L
• moles per kJ
• moles per mL

True or False? The higher the concentration of a solution the less solutes it has in it.

• True
• False

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
