  1. The Mole II. Molarity

  2. substance being dissolved total combined volume A. Molarity • Concentration of a solution.

  3. A. Molarity 2M HCl What does this mean?

  4. MASS IN GRAMS MOLES NUMBER OF PARTICLES LITERS OF SOLUTION B. Molarity Calculations 6.02  1023 (particles/mol) molar mass (g/mol) Molarity (mol/L)

  5. B. Molarity Calculations • How many grams of NaCl are required to make 0.500L of 0.25M NaCl? 0.500 L 0.25 mol 1 L 58.4 g 1 mol = 7.3 g NaCl

  6. M = B. Molarity Calculations • Find the molarity of a 250 mL solution containing 10.0 g of NaF. 10.0 g 1 mol 42.0 g = 0.238 mol NaF 0.238 mol 0.25 L = 0.95M NaF
