The mass of the sun is approximately 4 × 10^30 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 answer:  A) 4.0 × 10^(−18)  B) 2.5 × 10^17  C) 5 × 10^17  D) 2.5 × 10^19  E) 4.0 × 10^42
Mass of sun = x * Mass of moon   x = Mass of sun / Mass of moon = (4 × 10^30) / (8 × 10^12) = 2^2*2^-3*10^18 = 10^18/2= 5*10^17   Ans. 5 × 10^17) 2.5 × 10^17
