In the formation of smog, nitrogen and oxygen gas react to form nitrogen dioxide:
N2(g)+2O2(g)→2NO2(g)How many grams of NO2 will be produced when 2.1L of nitrogen at 840mmHg and 28∘C are completely reacted?
I know that you use the equation n=PV/RT to get the number of moles of nitrogen. What I am stuck on is getting the moles of NO2
