1. Do you know your mole equalities? Answer: True or False

2. 1 atom = 6.022 x 10 23 g

3. False! That is a HUGE mass for 1 atom.

4. 1g Ca = 1.66 x 10 -24 atom Ca

5. False! You can’t have a fraction of an atom.

6. 1 amu = 1.66 x 10 -24 g

7. True!

8. 1 g Si = 28.08 atoms Si

9. False! Again, you can’t have a fraction of an atom.

10. 1 g = 6.022 x 10 23 atoms

11. False! Well, it is true for one element.

12. 1g/mol = 6.022 x 10 23

13. False!

14. 1 mol Ca = 40.08 g Ca

15. True!

16. 6.022 x 10 23 g Ca =1 mol Ca

17. False! Never put Avogadro’s number with grams.

18. 1 mol = 6.022 x 10 23 amu

19. False!

20. 1 mol = 6.022g

21. False! There are no elements with an atomic mass of 6.022g.

22. 1 atom = 6.022 x 10 23 g

23. False!Still.

24. 1 mol = 6.022 x 10 23 g/atom

25. False!

26. 1 mol = 6.022 x 10 23 particles

27. True!

28. 1amu = 6.022 x 10 -23 g/mol

29. 1g/mol = 6.022 x 10 23 False!

30. 1amu = 6.022 x 10 -23 g/mol

32. False!

33. 1 atom Boron =1.795 x 10 -23 g B

34. True! 10.81g B x 1 mol B =g/atom mol 6.022 x 10 23 atoms
