Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOX") that are of interest to atmospheric chemistry. It can react with itself to form another form of NOx, dinitrogen tetroxide. A chemical engineer studying this reaction fills a 75 L tank with 31. mol of nitrogen dioxide gas. When the mixture has come to equilibrium she determines that it contains 12. mol of nitrogen dioxide gas. The engineer then adds another 7.8 mol of nitrogen dioxide, and allows the mixture to come to equilibrium again. Calculate the moles of dinitrogen tetroxide after equilibrium is reached the second time. Round your answer to 2 significant digits.

Transcribed Image Text:Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOx") that are of interest to atmospheric chemistry. It can react
with itself to form another form of NOx, dinitrogen tetroxide.
A chemical engineer studying this reaction fills a 75 L tank with 31. mol of nitrogen dioxide gas. When the mixture has come to equilibrium she
determines that it contains 12. mol of nitrogen dioxide gas.
The engineer then adds another 7.8 mol of nitrogen dioxide, and allows the mixture to come to equilibrium again. Calculate the moles of
dinitrogen tetroxide after equilibrium is reached the second time. Round your answer to 2 significant digits.
