21. The thickness of one page in your chemistry textbook is about 0.0065 cm. How many meters is this?

22. What is the thickness of one page in your chemistry book in meters? 0.0065 cm cm 0.01 m = 0.000065 m

23. How many meters high would a stack of one mole of pages be?

24. 6.02 x 10 23 pages page 0.000065 m = 3.9 x 10 19 m

25. The distance to the moon is 380,000,000m. If you took your stack of papers from problem 6 and broke it down into smaller stacks, how many stacks of papers could you make from the earth to the moon?

26. 3.9 x 10 19 m The distance to the moon is 380,000,000m. If you took the 3.9 x 10 19 m stack of papers, how many stacks of papers could be made from the earth to the moon? 3.9 x 10 19 m 380,000,000 m stack = 1.0 x 10 11 stacks 1.0 x 10 11 stacks = 100,000,000,000 stacks

27. 1 mole of pages would be enough to build 100 billion stacks of paper to the moon.
