Question:

In testing for air pollution, a given air sample contained a total of 6.0 parts per million (ppm) of four pollutants, sulfur dioxide (SO₂), nitric oxide (NO), nitrogen dioxide (NO₂), and carbon monoxide (CO). The ppm of CO was 10 times that of SO₂ , which in turn equaled those of NO and NO₂. There was a total of 0.8 ppm of SO₂and NO. How many ppm of each were present in the air sample?
