Given the following equation: Ca(OH)2 + 2HNO3 --> 2 H2O
+ Ca(NO3)2
How many moles of water are produced when 2.27
moles of calcium hydroxide reacts with excess nitric
acid?
Please include your units and round to two decimal places.

4.45 moles of will be produced.

Explanation:

The balanced chemical equation:

As nitric acid is the excess reagent, calcium hydroxide is the limiting reagent as it limits the formation of product.

According to stoichiometry :

1 mole of produce = 2 moles of

Thus 2.27moles of will produce =  of

Thus 4.45 moles of will be produced.
