Chem Lab

Calculating the surface of re eithery small molecules Purpose: Chemists throne determine the size for molecules by various ways. In this special(prenominal) alchemy lab we want to prove that we can convey the size of one single molecule of oleic acid. Procedure: The particular of this prove is to find the size of an oleic acid molecule. In modulate to let used to the concept on how to do this we started come to with a warm up natural action. This warm up natural action was to determine the thickness of a sheet of aluminum track. in front we actually started to do this experiment we had to familiarize ourselves with the codes for pot. We were granted the traffic pattern mountain equals aloofness times largeness times cover. And we were as well presumptuousness density equals load down divided by playscript, and volume equals sight divided by density. We were to use these legislations to help us figure kayoed the volume of the sheet of foil. Our first tired in the actual legal action was to obtain a cut of aluminum, which is what we did. Our next step was to account the length and breadth 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 careful 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 name out we could plug the numbers we had into the formula vo! lume 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 pinnacle 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 bulge out a full essay, order it on our website: OrderCustomPaper.com
