Question

Suppose the average concentration of SO_(2) is measured to be 400mu (g)/(m^(3)) at 25deg C and 1 atm. Does this exceed the (24-hr) air quality standard of 0.14ppm ? If we approximate the atmosphere to be 79 percent nitrogen (N_(2)) by volume and 21 percent oxygen (O_(2)), estimate the density of air (k(g)/(m^(3))) at STP conditions (0deg C,1(atm)). 3. Suppose the average concentration of SO2 is measured to be 400 g/m3 at 25C and 1 atm. Does this exceed the (24-hr) air quality standard of 0.14 ppm? 4. If we approximate the atmosphere to be 79 percent nitrogen (N2) by volume and 21 percent oxygen (O2), estimate the density of air (kg/m3) at STP conditions (0C, 1 atm).
