Molarity (cont.)

What happens if Your Units Aren’t Given in Correct Units to Use the Molarity Equation? You Convert! How do you convert from moles to grams? How do you convert from milliliters to Liters?

Steps: Look at the units you are given in the problem. Do you have moles and Liters? Yes? Continue to step 2! No? Convert to the correct units! Plug your values into the molarity equation and solve for the unknown. Provide and answer with a unit!

Examples: You have 4.21 grams of NaCl in 1.65 L of solution. What is the molarity of the solution? Moles of NaCl: Molarity of the solution:

Examples: You have 0.5 mol of NaCl in 200 mL of solution. What is the molarity of the solution? Liters of Solution: Molarity of the solution:

Examples: You have 5.6 grams of NaCl in 300 mL of solution. What is the molarity of the solution? Moles of NaCl: Liters of Solution: Molarity of the solution:
