Question

7. Calculate the mass of one atom of sodium in gram.​

Answer 1

Answer:

This means that a single atom of sodium weighs 23 atomic mass units (AMUs), but it also means that one mole of sodium atoms weighs 23 grams. Hence 6.02 x 10^23 atoms of sodium weight a total of 23 grams. This means that if we divide 23 grams by the number of atoms, we should have the weight of a single atom.
