    Results The relative osmotic concentration was determined by measuring the percent change in mass of the potato tissues. Change in mass was measured of six solutions, each containing different levels of concentration (0, 0.1, 0.2, 0.3, 0.4, and 0.5). The percent change in mass decreased as sucros
