Although these quantities vary from one type of cell to another, a cell can be 2.2 m in diameter with a cell wall 45 nm thick. If the density (mass divided by volume) of the wall material the same as that of pure water, what is the mass (in mg) of the cell wall, assuming the cell to be spherical and the wall to be a very thin spherical shell? (Note that a thin spherical shell has volume V = At, where A = 4r is the surface area of the shell of radius r, and t is its thickness.)
