Sara and Sam are each working on a science project in which they need to research the individual masses of the nine planets (including the dwarf planet Pluto as the ninth planet). Sara completes her data for the planets' masses in kilograms while Sam's data is in milligrams. Use the following data tables to complete parts I, II, and III. Sara: Planet Mass (in kilograms) Jupiter 1.989 · 1027 Saturn 5.685 · 1026 Neptune 1.024 · 1026 Uranus 8.681 · 1025 Earth 5.974 · 1024 Venus 4.869 · 1024 Mars 6.419 · 1023 Mercury 3.302 · 1023 Pluto 1.31 · 1022 Sam: Planet Mass (in milligrams) Jupiter 1.989 · 1033 Saturn 5.685 · 1032 Neptune 1.024 · 1032 Uranus 8.681 · 1031 Earth 5.974 · 1030 Venus 4.869 · 1030 Mars 6.419 · 1029 Mercury 3.302 · 1029 Pluto 1.31 · 1028 Part I: Although both data tables represent correct data for each of the planet’s masses, who represented Jupiter’s mass with the most appropriate units, Sara or Sam? Part II: In two or more complete sentences, explain your reasoning for your answer in Part I. Part III: Use multiplication, division, and scientific notation to show that Sara’s representation of Jupiter’s mass in kilograms is equal to Sam’s representation of Jupiter’s mass in milligrams. Use milligrams to prove that 1.989 · 1027 kilograms is equal to 1.989 · 1033 milligrams. Use kilograms to prove that 1.989 · 1033 milligrams is equal to 1.989 · 1027 kilograms.
