Question

**Environmental Engineering**

The air quality standard for ozone (O_{3}) is 80 ppbv.

- Express that standard in micrograms per cubic meter at 1 atm pressure and 25
^{o}C. - At the elevation of Denver, the pressure is 0.82 atm. Express the sulfur dioxide standard at that pressure and a temperature of 15
^{o}C.

Step 1

The air quality standard for ozone is 80 ppbv.

The temperate (*T*) is 25ºC.

Convert the unit of temperature as follows:

Step 2

The pressure (*P*) is 1 atm.

The molecular weight of ozone is 16g/mol.

Convert the air quality standards for ozone in µg/m^{3} as follows:

Step 3

Answer:

The air quality standard for ozone...
