Answer:
6.52moles of H2O
Explanation:
First, let us calculate the number of moles of O2 containing 1.96x10^24 molecules. This is illustrated below:
1mole of O2 contains 6.02x10^23 molecules.
Therefore Xmol of O2 contain 1.96x10^24 molecules i.e
Xmol of O2 = 1.96x10^24/6.02x10^23 = 3.26moles
Now let us generate a balanced equation for the formation of water. This is illustrated below:
2H2 + O2 —> 2H2O
From the equation,
1mole of O2 produced 2moles of H2O.
Therefore, 3.26moles of O2 will produce = 3.26 x 2 = 6.52moles of H2O
