There is one part to this question. I need the answer in kg/m^3. Thank you!!

Pretend that galaxies are spaced evenly, 6.0 Mpc apart, and the average mass of a galaxy is \(1.0 \times 10^{11} \, M_{\odot}\). What is the average density (in kg/m\(^3\)) of matter in the universe? (Note: The volume of a sphere is \(\frac{4}{3} \pi r^3\), and the mass of the sun is \(2.0 \times 10^{30}\) kg.) [Text Box: __________ kg/m\(^3\)]
