  • Average density of the entire earth = c.5.5 g/cc.
  • Convert 6.0*10^24 kg to grams by multiplying by 1000. (=6.0*10^27 g) 1 ml = 1 cm^3 so 1 ml = .000001 m^3 divide 1.1*10^21 by .000001 (=1.1*10^27 ml) Density = grams/mL = 6.0*10^27 / 1.1*10^27 = 5.45 g/mL
  • You presented all the information in the question! You've done the hard part in finding the two figures you listed! All there's left to do is divide one number by the other! Duh de duh duh! Lousy question. Lousy! 5.5 grams per cubic centimeter. Second only to Mercury as densest of the planets, I believe.
