ProcedureFirst, a specimen, more specifically, any fruit was chosen to experiment on (in this case, grapes)Various solutions were prepared with a large range of solute concentrations including 0.0 mol/L, 0.2 mol/L, 0.4 mol/L, 0.6 mol/L, 0.8mol/L. In this particular experiment, Potassium Chloride, KCl, was the ideal solution chosen to undergo the calculation of osmolality. The tissue/grapes were cut into approximately equal sizes in the shape of oval. Cutting equal pieces had to be precise so it was ensured that every grape had the approximate same relative weight so the osmolarity would be as close as possible.The concentration of the saturated solution was then calculated to keep away from exceeding the actual value of the saturated solution. This was mainly because in the case where the concentration of the saturated solution did exceed the actual value, the data would be altered per say as the solute would not be able to bond to more molecules.The mass (grams) of solute corresponding to the necessary value of each range of moles of substance needed to be added to the solvent, water, was calculated.A weigh boat was weighed separately on a balance scale and was zeroed and its mass was recorded on a seperate sheet of paper. Soon after, the grapes that were cut and were decided upon to put into each one of the various concentration were weighed on the weigh boat on the balance scale and its mass was recorded. The mass of the grapes itself was recorded by subtracting the mass of the boat from the mass of the grapes and the boat.Then, 100 ml of distilled water was poured into the 5 graduated cylinders. Additionally, 5 beakers/clear plastic cup were obtained and 100 ml of distilled water was then poured separately into each cup.Each beaker was then labelled to differentiate the molarity of each of the solutes of KCl by its own.A scalpel was used to measure the amount the amount of KCl needed in grams to match the calculated values of the ranges of molecular concentration (0.2, 0.4, 0.6, 0.8). Any excess material on the scalpel was taken off as much as possible to limit any possibility of human errors which would alter the data and calculations.A tablespoon was then used to mix the water until the solute looked as if it had dissolved in the water and was able to rest for approximately 2 minutes.The 5 pieces of grapes were placed in each of the plastic cups corresponding to their solute concentration for approximately 24 hours After 24 hours, tweezers were used to take the grapes out of the cups containing the solutes and placed on 5 different labelled paper towels based on their concentration/molarity.The new grapes taken out of the solutes were placed onto the weigh boat which was then placed on top of the electric balance to determine the new mass of the grapes. The mass of the weigh boat calculated previously was then subtracted from the mass of the new grapes and the weigh boat to find the mass of the grapes itself.Once the mass of the new grapes was recorded for each molarity in the solutions, mass percent was then calculated to identify if there was any change in the mass.
