Suppose you arrive at a planet with the same mass per unit volume as the Earth but has 31 times Earth's radius. ?

What would you weigh on this planet compared with what you weigh on Earth?

    ge = ρ*r^3/r^2 = ρ*r

    gp = ρ*31^3*r^3/(31^2*r^2) = ρ*31*r

    gp/ge = ρ*31*r / (ρ*r) = 31 

    gravity on planet gp = 31 times gravity ge on Earth

    This is not a question about Chemistry.  It needs moving to Physics.
