In another day John has to measure the molar mass of a biological sample. Because the sample is not stalble at high or low temperatures, he decides to use osmosis to do the measurement. He adds different amount of the sample in 100 g of water against the other side of the osmometer pure water at room temperature 298.15 K. The pressure difference is measured and listed below.
