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
