Just a question I need checking ( if its not too much hassle).

Q.If a power plant burning 10,000 metric tons of coal per day with 10% excess air emits stack gas containing 100 ppm by volume of NO, what is the daily output of NO? (Assume coal is pure C).

A.

C + O2 → CO2

 (10000 metric tons of C) / 12.0108 g/mol x (1/1) x (44.0096 g/mol) x (100/ 1000000) = 3.66 metric tons of NO

It looks like you're using ppm by mass rather than volume...

Funny enough, but I was making the same mistake: using ppm by mass rather than volume( It's never too late to learn!
