Critical density

  1. Mar 13, 2007 #1
    hello, can anyone help me with this problem please:

    For H0=70 km/ S . MPC , what is the critical density (p0) for the universe in gm/cm^3? . if the average density of the universe is 5 * 10 ^ -28 gm/cm^3 , what is the fate of the universe.

    thanks ,

    You don't know ANY relevant equations? You need to make a start at a solution and prove you are stuck before anyone can help.
