Planners of an experiment are evaluating the design of a sphere of radius R that is to be filled with helium (0 oC, 1 atm pressure). Ultrathin silver foil of thickness T will be used to make the sphere, and the designers claim that the mass of helium in the sphere will equal the mass of silver used. Assuming that T is much less than R, calculate the ratio T/R for such a sphere.
