Using Sucrose Solutions to Determine Osmolarity of Potato Tubers Based on Weight By Thomas Pelikan Biology 200A Section 004 Kimberly Schmidt October 2‚ 2012 Abstract: In this experiment we were trying to determine the osmolarity of potato tubers by weighing them before and after incubating them in solutions of sucrose with varying molarities. To find the osmolarity we took a potato and used a cork borer to obtain seven samples of potato tubers. We then prepared seven beakers with concentrations

occur by moving water through the semi-permeable membranes. If the concentration of sucrose in the solution is less than the concentration of sucrose found in the potato‚ then the potato would decrease in mass. The opposite would occur as well‚ if the concentration of sucrose in the solution is more than that of the potato‚ then the potato would expand and gain in mass. In conducting this as an

Introduction The purpose of this lab was to build a calorimeter. The purpose of the calorimeter was to get the most energy from the burning chip to the 80g of water. Literature review In Physics‚ energy is the ability to do something. There are different kinds of energy in the world. Energy can’t be created or destroyed. It is conserved. All energy is conserved. Energy can be transferred between objects or systems by the interaction of forces. Energy comes in multiple forms‚ and the two most

impactful waves of immigration to the United States occurred as a result of the Irish Potato Famine. The famine occurred due to failure of Ireland’s potato crop in 1945 through 1949 (Mokyr 1).
