Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOx") that are of interest to atmospheric chemistry. It form another form of NOx, dinitrogen tetroxide. can react with itself to A chemical engineer studying this reaction fills a 25.0 that it contains 5.1 mol of nitrogen dioxide gas. L tank with 12. mol of nitrogen dioxide gas. When the mixture has come to equilibrium she determines The engineer then adds another 3.0 mol of nitrogen dioxide, and allows the mixture to come to after equilibrium is reached the second time. Round your answer to 2 significant digits. equilibrium again. Calculate the moles of dinitrogen tetroxide mol
