Which has more total atoms 1 mole of Cl2 or 1 mole of NH3?
Answer:
We know that 1 mole = 6.022* 10^23 particals.
1 mol of Cl2 = 2*6.023*10^23 = 12.046* 10^23 atoms
1 mol of NH3 = 4*6.023*10^23
= 24.045 * 10^23 atoms
1 mole of any substance has 6.02 x 10^23 atoms
The two things have the same number of molecules, but since Cl2 is composed of two atoms, and NH3 is composed of 4 atoms, NH3 will have more total atoms.
Wikipedia says a mole is the number of entities in Avogadro's Number, so 1 mole of NH3 will have more atoms in it.
