Answer : The number of moles of water produced are, 4.4 moles.
Explanation : Given,
Moles of oxygen gas = 2.2 moles
The given chemical reaction is:
By the stoichiometry we can say that, 2 moles of hydrogen gas react with 1 mole of oxygen gas to give 2 moles of water as a product.
From the balanced chemical reaction we conclude that,
As, 1 mole of oxygen gas react to give 2 moles of water.
So, 2.2 mole of oxygen gas react to give moles of water.
Thus, the number of moles of water produced are, 4.4 moles.
Answer: 90 g O2
Explanation: soution attached:
Balance first the chemical equation
CH4 + O2 => CO2 +2H2O
Convert mass of CH4 to moles
Use the mole ratio of CH4 and O2 from the balanced equation.
Convert moles of O2 to mass using the molar mass of O2.
