mole concepts

1. MOLE CONCEPT Presented by Jester Jay D. Torilla

2. LET US RECALL

3. 1. WHAT IS OUR FORMULA FOR CONVERTING THE ATOMS INTO MOLES ?

4. 2. WHAT IS THE METHOD THAT WE WILL USE IN SOLVING PROBLEMS ?

5. 3. HOW DO WE SOLVE THE MOLAR MASS OF A COMPOUND ?

6. ANALOGY IDENTIFY THE MISSING WORD BASED ON ITS EQUIVALENT. 1. 1 MOLE OF Zn : 6.02X10 23 1 MOLE : _________ 2. MOLECULES : COMPOUNDS ELEMENTS : ___________ 3. CO 2 : COMPOUND Cl : __________

7. OBJECTIVES At the end of the lesson the students should be able to: Understand the concept of moles in converting from grams to number of moles and number of particles; Solve for the unknown formula in a problem that is presented; and Appreciate the importance of the mole concept in everyday life.

8. FORMULAS OF MOLE MOLAR MASS - IS THE SUM OF ALL THE ATOMIC MASS PRESENT IN THE COMPOUND ELEMENT

9. FORMULA OF GRAMS TO MOLES No. Of grams x 1 mole/molar mass of the compound

10. FORMULA OF MOLES TO ATOMS # of moles x 6.02x1023/1 mole

11. PRACTICE PROBLEM how many moles are there in 10 g of aluminum?

12. IMPORTANT REMINDERS Remember that we can use the atomic mass of an element with unit as grams to represent the atomic mass of an element.

13. PRACTICE PROBLEM After converting the grams into moles we need to find the number of atoms from 0.37 mol of Al

14. PRACTICE PROBLEM Next, we are going to determine the molar mass, number of moles, and the number of particles.

15. PRACTICE PROBLEM Calculate the molar mass, number of moles and the number of particles in 50.0 g of iron (III) oxide, Fe2O3 (rust)

16. ACTIVITY Give the molar mass, number of moles and the number of atoms present in 37.0 g of propionic acid (C3H6O2) Use the GUFSA method

17. ABSTRACTION 01 2 What did you learn about our topic for today? What is the most essential learning in this topic? 3 What is the proper method that we should use in solving the mole concepts?

18. ASSESSMENT 1. WHAT IS MOLAR MASS? A. THE DIFFERENCE BETWEEN THE ELEMENTS OF A COMPOUND B. THE SUMMATION OF THE ATOMIC MASS OF THE ELEMENTS C. NONE OF THE ABOVE

19. ASSESSMENT 2. WHAT IS THE VALUE OF INE MOLE? A. 6.05X10 23 B. 6.02X10 25 C. 6.02X10 23

20. ASSESSMENT 3. LORENZO ROMANO AMEDEO CARLO AVOGADRO IS THE ITALIAN SCIENTIST THAT GIVE THE EQUIVALENT OF MOLE. A. TRUE B. FALSE C. CANNOT BE DETERMINE

21. ASSESSMENT 4. WHAT METHOD SHOULD WE USE IN CONVERTING THE NUMBER OF MOLES? A. GAPSA B. FUSGA C. GUFSA

22. ASSESSMENT 5. WHAT IS THE MOLAR MASS OF THE COMPOUND NaCl Na=22.9 Cl = 35.4 A. 56.26 B. 57.13 C. 57.12
