Please help. Can you tell me how to find
1. what is the weight of 1 mole of pure sodium (Na)?
2. How many molecules of Na are in 1 mole of Na?
one mole of Na? isn't it 22.98976928 grams? The mass of a mole of any element is equal to its atomic mass, in grams.
Sodium doesn't form molecules, just atoms when alone. 6.02 x 10^23 atoms will be in one mole of sodium.
