Molarity

Notes

Concentration- how much solute is dissolved in a specific amount of solvent or solution

​

Solute - thing being dissolved

Solvent - thing doing the dissolving

​

​

• Molarity (M) - moles of solute/ Liters of solution
• (on reference chart)

M = mol / L

​

Molarity Practice

• What is the molarity of a solution that contains 2.500 mol Sodium Hydroxide in 12.5 L solution?

​

• What volume of a 5.00 M H₂SO₄ solution contains 1.25 mol H₂SO₄?

​

• How many moles of KCl are in a 0.060M solution that is 1000.0 mL of solution?

​

• How many grams of MgCl₂ should be dissolved in 400.0 ml of water to make a 0.700M solution of MgCl₂?
