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

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

  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) C. Johannesson

  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 58.44 g 1 mol = 7.3 g NaCl C. Johannesson

  6. M = B. Molarity Calculations • Find the molarity of a 250 mL solution containing 10.0 g of NaF. 10.0 g 1 mol 41.99 g = 0.238 mol NaF 0.238 mol 0.25 L = 0.95M NaF C. Johannesson
