Answer:
Step-by-step explanation:
first we arrange with alike Diameter and Mass
planet Diameter Mass
Mercury 4.88*10^3 3.3*10^{23}
Jupiter 143.00 *10^3 18980.0*10^{23}
Earth 12.08*10^3 59.7*10^{23}
Mars 6.78*10^3 6.42*10^{23}
Saturn 121.00*10^3 5680.0*10^{23}
a.
Greatest Mass:-Jupiter
b.
Diameter of Mercury=4.88*10^3=4880 Km.
radius of Mercury:-4880/2=2440 km
c.
Mass of Jupiter-Mass of Saturn
=18980*10^{23}-5680*10^{23}
=(18980-5680)*10^{23}
=13300*10^{23}
=1.33*10^{27} kg
