Web18 okt. 2024 · The number of molecules in a mole is always the same number, called Avogadro’s number, which is 6.02 X 10 to the power of 23. So in 90g of H2O there are 5*6.02 X 10**23 = 30.10 X 10**23 = 3.010 X 10**24 molecules of H2O, and that is also the number of oxygen atoms. Mark me as a Brainlist. Find Physics textbook solutions?
