Question

A rough analysis of cell contents suggests their cytoplasm contains 5% by weight of solutes: 1% of protein of average molecular weight 45000; 1% is soluble lipids of molecular weight 400; 1% is sugars of molecular weight 170; and 2% is salts like KCl. What is the osmotic pressure inside these cells relative to pure water at 37 degree Celcius.
