Chemistry Molarity

How could you change a saturated solution to an unsaturated solution?

• Add solvent

• Add solute

What is the molarity of 3 mole of hydrochloric acid in 3 L of water. 

• 3 M

• 1 M

• 6 M

• 9 M

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
