Incorrect Question 3 0/1 pts An exhaust gas stream contains 2,000 ppm of a gaseous pollutant and 10% water content at 200C and 1.0 atm. The gaseous pollutant concentration at standard conditions of temperature and pressure (i.e., 20C and 1 atm, respectively) is most nearly 1,239 ppm 3,229 ppm none of the listed answer 2,222 ppm 2,000 ppm Hint: Cppm = (v2/V+)x106 Incorrect Question 5 0/1 pts An exhaust gas stream contains 2,000 ppm of a gaseous pollutant and 10% water content at 200C and 1.0 atm. The standard mass concentration of the pollutant gas is ____ the corresponding actual mass concentration. equal to It cannot be determined from the available data. greater than less than Hint: Cmass,s= Cmass,a:(P3/P2)-(T2/T3)
