  1. The Mole part II II. Molar Volume (a.k.a Molarity)

  2. Standard Molar Volume Equal volumes of all gases at the same temperature and pressure contain the same number of molecules. - Amedeo Avogadro At STP (Standard Temperature and Pressure): 1 mole of a gas occupies 22.4 liters of volume

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

  4. Molarity 2M HCl What does this mean?

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

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

  7. MASS IN GRAMS MOLES NUMBER OF PARTICLES LITERS OF SOLUTION Molarity Relationships 6.02  1023 (particles/mol) molar mass (g/mol) Molarity (mol/L) For any GAS at STP the L/Mol = 22.4 L

  8. 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

  9. M = 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

  10. Molarity Calculations • Calculate the volume in liter of 1.50 mol of Cl2 (gas) at STP? 22.4 L 1.5 mol = 33.6 Liters 1 Mol
