Air pollution Homework Answers Needed

Your Question:

To convert from µg/m3 to ppm, we use the following formula:

ppm = (µg/m3) / (molar mass of the gas / 22.414 L/mol)

14) The percent of carboxyl in the blood after 3-hour exposure to 50 ppm of CO is (b) 0.53%.

15) The settling velocity of a sphere of water with diameter 5 mm, density (p) of 106 g/m³, and viscosity (η) of 0.0172 g/m.s can be calculated using Stokes' law:

• Δρ is the density difference between the sphere and the fluid (106 g/m³ - 998.2 kg/m³ = 61.8 kg/m³)

• η is the viscosity of the fluid (0.0172 g/m.s = 0.0172 Pa.s)

Therefore, the answer is (c).

16) The most abundant air pollutant is (b) oxides of nitrogen (NOx).
