  2. Lesson #3 – Molar Mass of a Compound • To find the molar mass of a compound, we need to look at ____________________ • The molar mass ________________ • ___________________________________molecule or formula unit of that compound. • Similar to balancing equations; you will have to take into consideration how many atoms of each element in a compound by ______________________________________

  3. Sample Problem #1 • What is the molar mass of magnesium carbonate?

  4. Sample Problem #2 • What is the molar mass of calcium phosphate?

  5. Sample Problem #3 • How many grams are in 5.4 moles of H2O?

  6. Sample Problem #4 • Convert 657g CuSO4 to moles

  7. Homework! • Exercise 3, pg. 13 of the green book! • Really helpful exercise visually and practice doing calculations!

  8. Lesson #4 – Moles, Grams, and Particles • Let’s put it all together!

  9. The Magic Triangle!Relationship

  10. The Magic TriangleCalculations

  11. Sample Problem #1 • Convert 2.40 x 1024 molecules of N2 to grams

  12. Sample Problem #2 • A spoonful of sugar, C12H22O11, has a mass of 10g. Calculate the number of molecules in a spoonful of sugar.

  13. Sample Problem #3 • To check for blockages in the digestive tract, a drink of barium sulfate is given to patients before an X-ray. X-rays can not pass through barium sulfate, it’s presence would appear on the X-ray film and a blockage would be apparent. If 0.500 mole of barium sulfate is needed, how many grams of barium sulfate will be given to the patient?

  14. Sample Problem #3

  15. Homework! • The rest of the questions on pg. 15 and the questions from the text!! • Lab on Wednesday!! • Re-writes are here before the lab! • See you then!!
