Part A In the fall of 2002, a group of scientists at Los Alamos National Laboratory determined that the critical mass of neptunium-237 is about 60.0 kg. The critical mass of a fissionable material is the minimum amount that must be brought together to start a chain reaction. Neptunium-237 has a density of 19.5 g/cm³. What would be the radius r of a sphere of neptunium-237 that has a critical mass? Express your answer in centimeters to three significant figures. ▸ View Available Hint(s) r = 跖 ΕΠΙ ΑΣΦ 0 ? cm
