Answer:
136.5moles of H2O
Explanation:
First, let us write a balanced equation for the reaction of Hydrogen to produce water. This is illustrated below:
2H2 + O2 —> 2H2O
Molar Mass of H2 = 2x1 = 2g/mol
Mass of H2 from the question = 273g
Number of mole = Mass /Molar Mass
Number of mole of H2 = 273/2 = 136.5moles
From the equation,
2moles of H2 produced 2moles of H2O.
Therefore, 136.5moles of H2 will also produce 136.5moles of H2O.
