Re: mass vs density

my thoughts on the 'its mass suggest something denser than an iron core' question are. What if, unlike us with our 70% surface water, it has something like, 10% surface water, and that extra 60% surface is something like a much more dense version of 'rock' than we are used to. Or, it's Core is just much 'larger' proportionately than ours.
