The mass of Mars is about 6.421x10^20 metric tons. The mass of the sun is about 1.998x10^27 metric tons. About how many times the mass of Mars is the mass of the sun? Give your answer in scientific notation.

Answer 1

It's asking, 'How many times would the mass of Mars 'fit into' the mass of the Sun'? Well, the mass of Mars would go into the mass of the Sun.

m(sun)/m(mars)=1.998×10^27/6.421×10^20=3111664.85=3.112×10^6
