Answer:2000 timesStep-by-step explanation:GivenSara:[tex]Mercury = 3.302 * 10^{23[/tex][tex]Saturn = 5.685 * 10^{26[/tex]Sam:[tex]Mercury = 3.302 * 10^{29[/tex][tex]Saturn = 5.685 * 10^{32[/tex]To determine the number of times, the mass of Saturn is greater than the mass of Mercury, we simply do the following:[tex]Times = \frac{Saturn}{Mercury}[/tex]Using Sara's measurement; this gives:[tex]Times = \frac{5.685 * 10^{26}}{3.302 * 10^{23}}[/tex]Apply law of indices[tex]Times = \frac{5.685 * 10^{26-23}}{3.302}[/tex][tex]Times = \frac{5.685 * 10^3}{3.302}[/tex][tex]Times = 5.685/3.302 * 10^3[/tex][tex]Times = 1.72 * 10^3[/tex]Approximate[tex]Times = 2 * 10^3[/tex][tex]Times = 2000[/tex]
