# How Many Moles Of H2O Are Required To Produce 4.5 Moles Of HNO3 According To The Following Reaction: 3NO2+H2O = 2HNO3+NO

## X=2.25 mol

## To solve this problem, we need to use stoichiometry.

From the balanced chemical equation, we can see that 1 mole of H2O is needed to produce 2 moles of HNO3. Therefore, we can set up the following proportion:

1 mole H2O/2 moles HNO3 = x moles H2O/4.5 moles HNO3

where x is the number of moles of H2O needed.

Simplifying the proportion by cross-multiplication, we get:

2x = 4.5

Solving for x, we get:

x = 2.25 moles H2O

Therefore, 2.25 moles of H2O are required to produce 4.5 moles of HNO3.

## from the reaction equation ... each mole of H2O results in two moles of HNO3

(moles H2O) * 2 = (moles HNO3) ... ? * 2 = 4.5
