1-How many atoms of nitrogen are in 1.00 mole of nitrogen gas?
2-How many molecules of oxygen are in 1.00 mole of Oxygen gas?
3-how many grams of iron do you have in 1.00 of iron?
But can you further elaborate on the first 2 questions?
Oxygen and Nitrogen are both diatomic so the 1 Mole of each should be doubled. In other words you would need to multiply Avogadros number by 2 which would equal approximately 12.044*10^23.
Yes that is right one mole of any element has a mass in grams which is equal to its atomic number and has exactly 6.02*10^23 atoms. Oxygen and Nitrogen are both diatomic so we will multiply Avogadros number by 2
