mole-mass problem:
Water decomposes to produce hydrogen gas and oxygen gas. How many moles of oxygen would be produced from 10.0 moles
water? 2 H2O → 2 H2 + O2

Respuesta :

Answer:

5.00 mol O₂

Explanation:

  • 2H₂O → 2H₂ + O₂

In order to solve this problem we will need to convert moles of water to moles of oxygen. We will do that using the stoichiometric coefficients, as follows:

  • 10.0 mol H₂O * [tex]\frac{1molO_2}{2molH_2O}[/tex] = 5.00 mol O₂

Thus 5.00 moles of oxygen would be produced from 10.0 moles of water.
