Hi quick question because I'm a little confused. I came across a problem and was just wondering; when it asks how many atoms are in a molecule, is it asking how many moles are in it or is that something completely seperate?

Thank you!!

Getting moles is a great start but, you have to find atoms and to do this you convert by using Avogrado's number.

Hope this help!

I'm pretty sure if it's asking how many atoms are in a molecule, it would be asking you to count up the number of atoms present in the molecular formula (for example, H2O has three atoms in a molecule, 2 hydrogens and 1 oxygen).

If they give you the mass of the compound, you convert it to moles, with the molar mass, and then multiple it by Avogadro's number! That's the amount of atoms that are in each mole of anything.
