Hii there !
The reaction accompanying production of water in this case would be -
![\green{ \underline { \boxed{ \sf{H_2+ (1)/(2)O_2\longrightarrow H_2O}}}}](https://img.qammunity.org/2023/formulas/chemistry/high-school/scjc740kr9klh93zbzol2zdcexoc6gfhpv.png)
Thus ,by observing the reaction, we can conclude that 1 mole of Hydrogen (H
)react with 1/2 mole of oxygen(O
)to produce 1 mole of water (H
O)
Therefore, 37.0 moles of hydrogen(H
) will be required to produce 37.0 moles of water.
Hope it helps.
