Question

How many moles of H2 would be required to produce 37.0 moles of water?

Answer 1

Hii there !

The reaction accompanying production of water in this case would be -

$\green{ \underline { \boxed{ \sf{H_2+ \frac{1}{2}O_2\longrightarrow H_2O}}}}$

Thus ,by observing the reaction, we can conclude that 1 mole of Hydrogen (H$_2$)react with 1/2 mole of oxygen(O$_2$)to produce 1 mole of water (H$_2$O)

$\implies$Therefore, 37.0 moles of hydrogen(H$_2$) will be required to produce 37.0 moles of water.

Hope it helps.
