In the reaction O2+2NO->2NO2 what is the ratio of oxygen reacted to nitrogen dioxide produced? Nitrogen monoxide to nitrogen dioxide?

Question

We had to calculate the concentration of each, for which I have O2=-1.01x10^-5, NO=-2.03x10^-5 and NO2=2.04x10^-5.

I'm not sure how to do it but what I got was 1O2:2NO2 and 1NO:1NO2.

We also have to compare it to the balanced equation and I don't understand what to do for that part.

Answer 1

ratio? O/NO=1/2
No/NO2=2/2=1/1
