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?

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

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.
