Chem Lab

Calculating the size of re eachy small molecules Purpose: Chemists john determine the size for molecules by various ways. In this special(prenominal) chemical science lab we want to prove that we can convey the size of one single molecule of oleic acid. Procedure: The particular of this experiment is to find the size of an oleic acid molecule. In modulate to thread used to the concept on how to do this we started come to with a warm up natural action. This warm up use was to determine the thickness of a sheet of aluminum vex. in front we actually started to do this experiment we had to familiarize ourselves with the codes for pot. We were precondition the traffic pattern mountain equals aloofness times largeness times aggrandisement. And we were as well stipulation density equals mess divided by bulk, and volume equals chain reactor divided by density. We were to use these legislations to help us figure away the volume of the sheet of foil. Our first tired in the actual action was to obtain a cut of aluminum, which is what we did. Our next step was to verse the length and comprehensiveness of the aluminum foil and record them on our data sheet. We did that with a standard ruler. Next, we had to measure the mass of the foil and record that on our data sheet. We took our piece of foil and heedful it on a balance, got our number, and put down it.

After we got all of our data we needed to find the volume of the piece of foil, we were given the information that the density of aluminum is 2.7 cm/g. With the information we knew and were given, we order out we co uld plug the numbers we had into the formula! volume equals mass divided by density. We plugged our mass and density into that equation, worked it out and got our volume. After that, our next step was to lead the thickness, or meridian of the foil. We used the formula that we were given, which was volume equals length times width times height. We plugged our volume, length, and width into the formula and solved for height. The height is the thickness of the foil. This activity was very equal to...If you want to draw off a full essay, order it on our website: OrderCustomPaper.com
