Moles in chemistry

1.40K viewsChemistryOther

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! 🙂

an atom has a given mass, for example C6 (carbon) has 12 units of mass per atom

mole is the number of C6 atoms you need for it to be exactly 12 as well, but this time grams

and for all substances this is the same number (just like you always need 1000 1kg packets to get 1000kg total mass, regardless of what these packets contain it will stay the same)
