We learned that it is spelt the same as the animal mole, but is actually a number! We then got a worksheet that showed us how big the number mole actually was. When you here the number you think it is big, but this worksheet showed how humongous the number is. This day we also got our colored periodic table of elements which shows us the element and its molar mass. We learned that the Molar Mass of every element is on the periodic table. The last thing we did was do a lab on molecules of water in your mouth, and how many Pepsi cans are needed to contain 8.45*10^23 atoms of aluminum. I won't write to much in this about the experiment because I already did that in my conclusion, but the real purpose of this was to get us used to converting between moles and molecules. Throughout the week we did plenty of this. I did not really like having to write the For Every Statements for each one because often times this made me over think every question. Otherwise, I think the practice was useful because it got us used to doing the calculations. The last thing that we learned was percentage composition. This is a very easy topic to understand. All you do is take the compound you are using and take the one you want and divide it by the total. This is hard to understand so I will give an example. If you have water, so H(2)O and you want to find the percentage composition that Hydrogen is of water, you take 2, which is the atomic mass of 2 hydrogen's, and divide it by 18, which is the total atomic mass of water. So you take what you want to find, divided by the total.
If I was to look back on the week I would say I learned and understand everything about moles. Like I said earlier I didn't really like having to write the For Every statement every time at the beginning of the unit. I also thought we did to many examples, but I can say I understand Moles well.
