Question

the mass of planet Mercury is 3.3x10^23 kilograms the mass of planet Jupiter is 5.8 x 10^3 times the mass of planet Mercury. planet Jupiter is 3.2×10^2 times the mass of planet Earth.1. using scientific notation what is the mass of planet Jupiter?2. using scientific notation what is the mass of planet earth?

Answer 1

We let mass of Mercury = M
mass of Jupiter = J
mass of Earth = E

M =3.3x10^23 kilograms

J = (5.8 x 10^3)M
J = (5.8 x 10^3)(3.3x10^23 kilograms)
J = 1.914x10^27 kilograms

J = (3.2×10^2)E
1.914x10^27 kilograms = (3.2×10^2)E
E = 5.98x10^24
