  8. Mass of one atom of nitrogen

  9. 14.01amu

  10. Mass of one mole of chlorine

  11. 35.45 g/mol

  12. Mass of 6.022 x 10^23 atoms of nitrogen

  13. 14.01 g/mol

  14. What are the units used behind Avogadro's number?

  15. Particles, atoms, molecules, ions, formula units

  16. If the unit is grams, what number precedes it?

  17. The mass from the periodic table; this changes depending on the element

  18. An atom

  19. microscopic

  20. 0.5 moles Be

  21. macroscopic

  22. 6.022 x 10^23 ions

  23. macroscopic

  24. 50 molecules of glucose

  25. microscopic, that's .00000000000000 0000000083 moles

  26. .02 moles of carbon

  27. macro, that's 1.2 x 10^22 atoms

  28. How much is a mole of a sustance?

  29. it's specifically 6.022 x 10^23 particles

  30. What unit is used for molar mass?

  31. g/mol

  32. What is the molar mass of selenium?

  33. 78.96g/mol

  34. What is the molar mass of CO2 (carbon dioxide)?

  35. 12.01g/mol + 2(16.00g/mol)= 44.01g/mol

  36. Why is the molar mass of vanadium 50.94g/mol?

  37. because the vanadium-51 isotope is most abundant in nature

  38. 1 atom = 6.022 x 10^23 g

  39. False, that's a huge number!

  40. 1 g = 28.08 atoms Si

  41. False, you can't have fractions of atoms

  42. 1 mol C = 12.01amu C

  43. false, 1 mole is macroscopic, the unit is not amu

  44. 1mole = 6.022 x 10^23 ions

  45. True!

  46. 6.022 x 10^23 moles= 1 atom

  47. False, moles are not a possible unit for Avogadro's number

  48. How many moles are in 11g of nitrogen, N?

  49. 0.79mol N
