Mass To The Nearest 0 1
569 wordsLab Report Title: The Concept and Measurement of Density Purpose: To gain an understanding of the physical property of density. To gain skill in measurement of mass and volume, in addition to the construction of graphs and the physical interpretation of slope. Procedure: Part 1 Regular solids 1. Use the metric ruler to determine the length, width, and height of aluminum and iron cubes to the nearest 0.5 cm. 2. Use the balance to measure the mass of each item listed above to the nearest 0.1 g. Pa...

Mass Of The Potato Chip
785 wordsOsmosis Investigation Introduction & Aims At present I am investigating Osmosis, and I have devised a experiment to investigate the rate of it. I have been provided with potatoes, and all the common laboratory equipment. I will look at 2 variables, one discontinuous, one continuous. For my discontinuous veritable I have chosen TYPE OF POTATO. I will have 3 different types of potato, chosen randomly, and numbered A, B & C. For my continuous veritable I have chosen TIME. Every 5 minutes, I will re...

Percentage Of Water In Copper Sulfate Pentahydrate
1,082 wordsPercent Composition Of Water In Copper SUlfate Pentahydrate (Lab Report Version) Abstract The percentage of water in Copper Sulfate Pentahydrate was found. Copper Sulfate was heated in a crucible to evaporate the water. The mass was weighed to find the difference before and after heating. By comparing these masses, the percentage of water was found. The percentage of water was found to be 34%. Theory Copper Sulfate Pentahydrate or Cu SO + 5 H O is a solid compound. To find the percentage of wate...

Water Potential Of The Cells
1,262 wordsDETERMINATION OF THE WATER POTENTIAL OF POTATO TUBER CELLS. Method. Five sucrose solutions with varying molarity and one control containing distilled water were prepared and poured into test tubes. The potato discs were dried, weighed and added to the test tubes. The discs were then weighed again after a period of 24 hours. The percentage change in mass was then calculated. Apparatus. Specimen tubes with stoppers x 6 1 cm 3 diameter cork borer razor blade filter papers balance distilled water su...

Water Molecules From The Chip
1,046 wordsBackground Information. I think that this practical will be based on osmosis because, Osmosis is the random movement of water molecules from a high concentration to a low concentration. This will then happen between the chips and the liquid in the McCarthy bottles. This already tells us that the chips will vary in size from the concentration of water. Plan of the Experiment. Method 1 Firstly we shall set up the experiments by getting the apparatus and the materials (potatoes) ready. We shall the...

Laboratory Stocklaboratory Stock Part B 1
2,047 wordsPURPOSE: In this particular laboratory experiment, we are going to determine the molar mass of an unknown gas, from the gas density. We are also going to use gas density, along with the kinetic molecular theory, to explain the behavior of gas filled balloons. Finally, we are going to demonstrate the effects of temperature and pressure changes of gasses. PROCEDURE: We are using the experimental procedure as described in our laboratory manual. University of Wisconsin - River Falls Laboratory Manua...

Ammonia Concentration In The Big Crayfish Water
536 wordsAmmonia Excretion As A Function Of Body Size In Crayfish INTRODUCTION The breakdown of proteins and nucleic acids during metabolism gives rise to excess nitrogen which must be rid of by living organisms. Aquatic animals, such as the crayfish we studied in lab, the excess nitrogen is excreted in the form of ammonia (NH 3) Because ammonia is highly soluble in water, the ammonia is able to be excreted across the gills into the water. The rate at which this takes place is related to body mass of the...

Total Mass Of A Water Molecule
556 wordsMass Spectrometer A mass spectrometer produces charged particles (ions) from the chemical substances that are to be analyzed. The mass spectrometer then uses electric and magnetic fields to measure the mass (weight) of the charged particles. There are many different kinds of mass spectrometers, but all use magnetic and / or electric fields to exert forces on the charged particles produced from the chemicals to be analyzed. A basic mass spectrometer consists of three parts: 1. A source in which i...

Percent Of Water In A Hydrate
718 wordsAbstract: When salts are crystallized from water, they take up a fixed amount of water as part of their crystal structure. The water that is retained by the salts is just enough to give the geometry and the bonding needed of a crystal. The quantity of water that is retained is called water of hydration or water of crystallization. The crystal formed is called a hydrate. A hydrate, usually found in nature, is a chemical compound made of an exact amount of water and another substance. Water of hyd...

Water And 0 2 M Solution
331 wordsObjective Determine the relationship between concentration of solution and osmosis Protocol Materials: six 30 ml dialysis tubes, clamps, tube holders, 250 ml beakers, distilled water, sucrose in 0.2 M, 0.4 M, 0.6 M, 0.8 M, 1.0 M concentrations, electronic balance Six 30 ml dialysis tubes were obtained. The bottoms of the bags were clamped to create bags. Twenty-five ml of each of the following were added to the separate bags: distilled water, 0.2 M sucrose, 0.4 sucrose, 0.6 M sucrose, 0.8 M sucr...
