Answer
The mole ratio of H2O to H2SO4 is 2:1
Explanation
Given chemical equation:
[tex]2\text{NaOH }+H_2SO_4\rightarrow2H_2O+Na_2SO_4[/tex]From the balanced chemical equation above, 2 moles of NaOH react with sulfuric acid, 1 mole of H2SO4, to produce 2 moles of water and 1 mole sodium sulfate.
So, from the chemical equation, you have a 2:1 mole ratio between H2O and H2SO4
