question

Most membranes of animal cells contain about 60% protein and 40% phosphoglycerides. (a) Calculate the average density of a membrane, assuming that protein has a density of 1.2 g/cm^3 and phosphoglyceride a density of 0.92 (g/cm^3). (b) If a sample of membrane material were centrifuged in NaCl solution of 1.05 specific gravity, would it sediment or float?
