27. For the reaction 2 H2 + O2 → 2 H20, how
many moles of H2O would you get from 2.0169
H2?
a. 2.016 mol H2O b. 1 mol H2O
c. 2 mol H2O
d. 4 mol H2O

2H₂ + O₂ → 2H₂O

You will need to use stoichiometry to solve this problem.  The stoichiometric factor will need to relate H₂ and H₂O.  From the equation, we see that for every two H₂ molecules that react, two H₂O molecules are produced, so the factor is .  The twos reduce, making this a one-to-one ratio.

a. 2.016 mol H₂O

Hint: Because of significant figures, the other three answers would be wrong by default.

idk what the question is about
