Question

How many moles of O2 are present in each state how many moles of O2 are present in 3*20^23molecules?

Answer 1

Answer:

Well, one mole is equal to Avogadro’s Number, or 6.02210 x 10^23 particles. Since you are not talking about the amount of oxygen atoms in 3 moles of O2, no extra multiplication is needed to compensate for that.

3 moles x (6.02210 x 10^23) O2 molecules per mole = 1.80663 x 10^24 O2 molecules.
