Question
(5) Locate the current NAAQS annual average mixing ratio value for nitrogen dioxide (NO2) (Textbook Table 1.3 = 0.053 ppm ) Convert the mixing ratio
(5) Locate the current NAAQS annual average mixing ratio value for nitrogen dioxide (NO2) (Textbook Table 1.3 = 0.053 ppm ) Convert the mixing ratio to concentration units (g/m3 ) in two different locations: a) Northway, Alaska at a barometric pressure of 31.85 in Hg and temperature of -31 o C (Answer 130 g/m3 )
b) Cameron, Texas at a barometric pressure of 948 mb and temperature of 27 o C (Answer 92.6 g/m3 )
c) Convert the concentration of NO2 in Northway to the concentration in Cameron by using the ratio of the density of the air mix at the two locations. State any assumptions. Discuss any minor difference with the value you obtained in b).
