9.The land area of Greenland is 840,000 mi2 with only 132,000 mi2 free of perpetual ice. The average thickness of this ice is 5000 ft. Estimate the mass of ice to two significant figures. The density of ice is 0.917 g/cm3.

Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reactants. consider 1 mole of tritium plus 1 mole of deuterium to be a mole of “reactions” (total molar mass = 5 grams).
