10) How many molecules and atoms are in 3 moles of N,H?

Question

Question

Answer 1

Answer #1

1 molecule of N₂H₄ contains 2 nitrogen atoms and 4 hydrogen atom.

Total atoms = 6

1 mole N₂H₄ is 6.022*10²³ molecules - (Avogadro number)

3 moles N₂H₄ = 3*6.022*10²³ molecules = 18.066*10²³ molecules

Number of atoms in 3 moles of N₂H₄ = 6*18.066*10²³ = 108.396*10²³ atoms= 1.08396*10²⁵ atoms
