Question

NOx from the exhaust of motor vehicles may contribute to smog and ozone. It is emitted from vehicles as mainly NO and NO2. It is regulated as NOx using the units of equivalent tons of NO2 (equivalent in the form of moles of N). If motor vehicles in the Seattle area on July 1st, 2008 emitted 2100 tons of NOx, and on a mass percent basis 80% was NO and 20% was NO2, what are the actual tons of each of these compounds emitted?

Explanation / Answer

Tons of NO = x
Tons of N02 = y

We know x + y = 2100

80% of it was NO
So, 80% of 2100

80/100 * 2100

80 * 21

1680 tons of NO

Remaining 20% was NO2
Tons of No2 = 20/100 * 2100

= 20 * 21

= 420 tns of NO2

So ans :
1680 tons of NO
420 tons of NO2
