By using observations of the Doppler Shift of radiation coming from ionized gas in the nucleus of a galaxy, it is determined that the gas orbits the nucleus at a speed of 3000 km/s (convert to m/s) at a distance from the center of 20 light-years (convert to meters). Calculate the amount of mass within 20 light-years of the galaxy's center (in kilograms and solar masses). Make sure you show all parts of your solution and don't forget units.
