hey this is kinda a dumb question lol, but what is the diffrence between atoms and moles when you're calculating, so for example in order to calculate the mol of Carbon youd take its atomic number and multiply it by 2 so 6x2 then you take the grams of carbon and divide it by 12 thats how u get moles, but does that apply to atoms too?

Vocaloid:

Molar mass, in general, is *not* the atomic number * 2. When you get to higher elements, the # of neutrons starts exceeding the # of protons, and thus the molar mass is much greater than 2* the atomic number. To calculate moles of any substance, you divide its mass in grams/ molar mass in grams/mol to get moles. This could apply equally for individual atoms, molecules, etc.

Walen:

vocaloid i closed this for a reason lol, i realised i was being a dum boi, sorru for notifying u

Walen:

and also i thought for atoms i would need to take the moles and multiply it by the avogadro number so (mol x 6.023 x 10^23) but this raises an interesting question for me, when it comes to avogadros number do i need the 0.23 or can i just go with 6 x 10^23?
