The mass of the sun is approximately 2 × 10^20 kg and the mass of the moon is approximately 8 × 10^12 kg. The mass of the sun is approximately how many times the mass of the moon?  Choose the correct choice from the following answers
A) 4.0 × 10^(−18)	B) 2.5 × 10^17	C) 2.5 × 10^7	D) 2.5 × 10^19	E) 4.0 × 10^42
Mass of sun = x * Mass of moon   x = Mass of sun / Mass of moon = (2 × 10^20) / (8 × 10^12) = 2*2^-3*10^8 = 10^8/4 = 2.5*10^7   Ans. 2.5 × 10^7) 2.5 × 10^7
<result>C</result>
The mass of the sun is approximately 2 × 10^20 kg and the mass of the moon is approximately 8 × 10^12 kg. The mass of the sun is approximately how many times the mass of the moon?
