This explore lab was quite the doozy. First, we matched 50 beans from 5 different types! After we massed them we found their relative mass and then ranked them from lowest to highest, in mass that is. We then counted exactly how many beans fit into the relative mass by adding them one-by-one to the balance beam until we reached the relative mass. This created the “pot”. Little to our knowledge the “pot” too had a double meaning! The pot represents the famous MOLE! No this is not the dirt burrowing creature, the mole is simply just another unit of measurement that makes chemistry that much easier. You can see the moles relation to the pot because the pot is measuring how many beans make up the relative mass of a certain type of element. Moles do this too. Moles use the relative mass of each element to find the amount of any element substance. The relative mass was used to find the number of beans in the pot. But why? Well, you divide the mass of the 5 different types of 50 beans by the smallest bean mass you have, which in this case was the lentil at 2.532g. This gives you the relative mass! You use this mass to determine the number of beans in the pot because the relative mass is approximately the mass of the pot. So you then add your beans and you can determine how many beans are in each pot. A pot is a model for the mole because the mole, like the pot, also hold multiple atoms, or beans, according to the relative (or atomic) mass. The average atomic mass is used for the mole because scientists have found using the average weight for the atom instead of the different isotopic versions worked out better. Why? Because it is the average! Sometimes it will be higher is some atoms and sometimes it will be lower, but don’t fret! Overall the atomic mass is the better choice because it gives scientists, like you and me, a closer look at the atom itself.
