A test of an automobile engine exhaust revealed that 3.7g of NO2 was emitted in 10 minutes of operation. How many moles of NO2 would this engine release if it were used for a 45 minute commute, assuming that this measured number is representative of the emission under all circumstances

asked by PJcotieboi
  1. This is not a chemistry problem. A math problem and then a simple one.
    3.7g NO2 x (1 mol NO2/molar mass NO2) x (45 min/10 min) = ? mol in 45 min.
