1. Determine the number of protons in one NO2 molecule:
* Nitrogen (N): Nitrogen has an atomic number of 7, meaning each nitrogen atom has 7 protons.
* Oxygen (O): Oxygen has an atomic number of 8, meaning each oxygen atom has 8 protons.
* Total: In one NO2 molecule, there are 7 (N) + 8 (O) + 8 (O) = 23 protons
2. Calculate the total number of protons in one mole of NO2:
* Avogadro's Number: One mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, etc.).
* Total Protons: (23 protons/NO2 molecule) * (6.022 x 10^23 NO2 molecules/mole) = 1.385 x 10^25 protons
Therefore, there are approximately 1.385 x 10^25 protons in one mole of NO2 gas.
