I am trying to calculate the gravitational mass (in solar masses)  I have the formula M= V^2 R / G (4.31 x 10^-6)  The paperwork says our numbers should be big but I am coming up with .002 etc.  What am I doing wrong?

w at each of your chosen radii from the Ro able 1. velocity to determine the mass, M of the ty says that the total mass contained wit v²R M = column B in Table 1, R is the radius f nt which has a value of 4.31 x 10-6 in a X 10r ional Mass" column in Table 1. Your . It contains a lot of stars.
