How many molecules of water are produced when 8.93 * 1023 molecules of oxygen are reacted with
excess hydrogen gas in the reaction below?
2H2 + O2 → 2H2O
Use the following conversion factors to convert from molecules of oxygen to molecules of water: 1 mole O2/ 6.02 x 10^23 molecules O2, 2 mole H2O/ 1 mole O2, 6.02 x 10^23 molecules H2O/ 1 moles H2O
