Critical Density: H0=70km/s.MPC, Fate of Universe

[b_o3]

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 ,
