Hey guys. I’m struggling to understand the concept of moles, and was hoping someone could explain it a lot easier than in previous posts. I understand that a mole of something means that there is 6.022 x 10\^23 of that something (similar to the idea of 1 dozen = 12 things), but I don’t quite understand when for example 1 mole of Nitrogen is 14g.
If 1 mole of nitrogen means that there is 6.022 x 10\^23 nitrogen atoms, how does 1 mole of nitrogen equal 14g? Is it saying that 6.022 x 10\^23 nitrogen atoms (1 mole of nitrogen) is equal to 14g, since the mass of a nitrogen atom (single nitrogen atom) would be super small, and so we use moles to convert it into a reasonable mass for easier calculations e.g. 14g?
Hope that wasn’t too confusing :S
Thanks everyone! 🙂

Using your example of a dozen: a dozen chicken eggs have a weight in grams. A dozen quail eggs also have a weight in grams. They are different weights, but we can agree that there are a dozen of each thing.
A dozen atoms is not really enough to weigh in those units, so instead we use a much larger type of group called a mole. A mole of chicken eggs would have a different weight than a mole of quail eggs. A mole of nitrogen is a particular number of nitrogen atoms, and they also have a unique weight.
