Question

I need the answer for Earths mass and the mass and weight for Mars.

Answer 1

.9736 x 1024 kg. That’s a big number, so let’s write it out in full: 5,973,600,000,000,000,000,000,000 kg. You could also say the Earth’s mass is 5.9 sextillion tonnes and the mass of Mars is 7.08 x 1020 tons or 6.42 X 1020 metric tons
