Homework Statement
I can't get how they calculate that.
I'm not sure if there including H0 which I think is 70 or not but I've tried with and without and both don't work.
I get (3 * 70^2)/(8pi*6.67 * 10^-11) which is way off.
I also can't get the units that they arrive at
I get
km/s/Mpc * s^2/m^3kg which is
km(s)/Mpc/kg*m^3
