how many moles of H2O are produced when 5.00 mols of oxygen gas are used
With what reaction?
2H2 + O2 ==> 2H2O
5.00 mols O2 x (2 mol H2O/1 mol O2) = 5.00 x 2/1 = 10 mols H2O produced.
To determine how many moles of H2O are produced when 5.00 moles of oxygen gas (O2) are used, we need to refer to the balanced chemical equation for the reaction. Without the specific reaction, it is impossible to provide an accurate answer.
However, I can guide you on how to find the answer once you have a balanced chemical equation. Here's an example using the equation for the combustion of hydrogen gas (H2) with oxygen gas (O2) to form water (H2O):
2H2 + O2 -> 2H2O
The equation tells us that for every 1 mole of O2, we get 2 moles of H2O. Therefore, if we have 5.00 moles of O2, we can calculate the corresponding moles of H2O using the ratio:
5.00 moles O2 x (2 moles H2O / 1 mole O2) = 10.00 moles H2O
So, when 5.00 moles of oxygen gas are used, 10.00 moles of water would be produced in this example reaction.
