One mole of hydrogen peroxide H2O2 would consist of how many molecules?

To determine how many molecules are in one mole of any substance, we can rely on Avogadro’s number, which is approximately 6.02 x 10²³ molecules per mole. Therefore, regardless of the substance, one mole will always contain this fixed number of molecules.

In the case of hydrogen peroxide (H₂O₂), one mole would also contain 6.02 x 10²³ molecules. This means that the correct answer is:

a) 6.02 x 10²³

So, the answer reflects the universal principle that one mole corresponds to Avogadro’s number of particles, whether they are atoms, molecules, or other entities.
