Question

The mass of Uranus is about `8.7 times 10^22` metric tons. The mass of the sun is about `1.998 times 10^27` metric tons. About how many times the mass of Uranus is the mass of the sun?

Answer 1

Mass of Sun is `2.297xx10^4` times mass of Uranus

Explanation:

As the mass of the Sun is `1.998xx10^27` metric tons

and mass of Uranus is `8.7x10^22` metric tons

Mass of Sun is `(1.998xx10^27)/(8.7xx10^22)` times mass of Uranus or

`1.998/8.7xx10^(27-22)` times or

`0.2297xx10^5` or `2.297xx10^4` times.
