Do you know your mole equalities?

Do you know your mole equalities?. Answer: True or False. 1 atom = 6.022 x 10 23 g. 1 atom = 6.022 x 10 23 g. False! That is a HUGE mass for 1 atom. 1g Ca = 1.66 x 10 -24 atom Ca. 1g Ca = 1.66 x 10 -24 atom Ca. False! You can’t have a fraction of an atom. 1 amu = 1.66 x 10 -24 g.

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

  2. 1 atom = 6.022 x 1023 g

  3. 1 atom = 6.022 x 1023 g False! That is a HUGE mass for 1 atom.

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

  5. 1g Ca = 1.66 x 10-24atom Ca False! You can’t have a fraction of an atom.

  6. 1 amu = 1.66 x 10-24 g

  7. 1 amu = 1.66 x 10-24 g True!

  8. 1 g Si = 28.08 atoms Si

  9. 1 g Si = 28.08 atoms Si False! Again, you can’t have a fraction of an atom.

  10. 1 g = 6.022 x 1023 atoms

  11. 1 g = 6.022 x 1023 atoms False! Well, it is true for one element.

  12. 1g/mol = 6.022 x 1023

  13. 1g/mol = 6.022 x 1023 False!

  14. 1 mol Ca = 40.08 g Ca

  15. 1 mol Ca = 40.08 g Ca True!

  16. 6.022 x 1023g Ca =1 mol Ca

  17. 6.022 x 1023g Ca =1 mol Ca False! Never put Avogadro’s number with grams.

  18. 1 mol = 6.022 x 1023amu

  19. 1 mol = 6.022 x 1023amu False!

  20. 1 mol = 6.022g

  21. 1 mol = 6.022g False! There are no elements with an atomic mass of 6.022g.

  22. 1 atom = 6.022 x 1023g

  23. 1 atom = 6.022 x 1023g False! Still.

  24. 1 mol = 6.022 x 1023 g/atom

  25. 1 mol = 6.022 x 1023 g/atom False!

  26. 1 mol = 6.022 x 1023 particles

  27. 1 mol = 6.022 x 1023 particles True!

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

  29. 1g/mol = 6.022 x 1023 False!

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

  31. 1amu = 6.022 x 10-23 g/mol

  32. 1amu = 6.022 x 10-23 g/mol False!

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

  34. True! 10.81g B x 1 mol B =g/atom mol 6.022 x 1023atoms
