An interplanetary expedition uncovered the remnants of an ancient civilization on Mars. They discovered two spherical objects made from previously unknown elements. The Martians had named one element Altrium, density 5.62 g/cm3, and the other element Hypotrium, density 2.77 g/cm3. Each sphere was exactly 10.00 cm in diameter. What was the difference in masses of the two spheres in grams? Volume of a sphere = (4/3)πr3. π = 3.1416.
