Please help me it’s just that I can’t remember how to do this it’s about the Mole and Stoichiomerty

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

the correct answer is a

i believe it is 40–40–20%
