How many moles of nitrogen monoxide will be generated when 0.83 moles of nitrogen dioxide gas reacts with water? 3NO2 + H2O 2HNO3 + NO

0.277 moles

0.415 moles

0.830 moles

1.000 moles

1.660 moles

A chemical equation lets us observe the ideal molar ratio between two chemical species that are taking part in a chemical reaction. This ratio is equivalent to the ratio of the stoichometric coefficients of the species. Therefore, the ratio between nitrogen dioxide and nitrogen monoxide is:

3 : 1

If 0.83 moles of nitrogen dioxide are present, the moles of nitrogen monoxide will be:

0.83/3

Moles of nitrogen monoxide are 0.277.
