Assuming that H0 = 70 km/s/Mpc, calculate the mass of the parent galaxy. (M = ? solar masses)

Note: The answer is NOT 9.05*10^17, 9.75*10^17, 1.87*10^33, 4.73*10^12, 4.19*10^11. These are the incorrect answers which I have enetered in the online assignment

Constants | Periodic Table A small satellite galaxy is moving in a circular orbit around a much more massive parent and just happens to be moving exactly parallel to the line of sight as seen from Earth. The recession velocities of the satellite and the parent galaxy are measured to be 6450 km/s and 6500 km/s, respectively, and the two galaxies are separated by an angle of 0.1° in the sky
