The density of the plasma membrane of a cell was found to be
1.07 g/mL. If the density of the lipid component is 0.91 g/mL and
the density of the protein component is 1.36 g/mL, what is the
percent composition (to the nearest ones) of the lipid component of
the membrane, assuming the plasma membrane consists only of the
lipid and protein components?
