Question 15 (2 points)
How many moles of H2O are produced when 5.32 moles of O2 react in the above equation?
If you are unsure how to do a mole to mole conversion, please see the example problem linked HERE.
a
4.56 moles of H2O.
b
0.13 moles of H2O.
c
6.21 moles of H2O.
d
7.89 moles of H2O.
To solve this problem, we need to use the mole ratio between O2 and H2O from the balanced chemical equation:
2 O2 + 2 H2 -> 2 H2O
From the balanced equation, we can see that 2 moles of H2O are produced for every 2 moles of O2 consumed.
Therefore, for every 1 mole of O2, 1 mole of H2O is produced.
Given that 5.32 moles of O2 are reacting, the same number of moles of H2O will be produced, which is 5.32 moles.
Therefore, the correct answer is:
c) 6.21 moles of H2O.
