  b. 37.0 mg/L
  c. 98.6 mg/L
  d. 43.8 mg/L

Question 2

Answer to Question 1

ANS: D
For example, air that is fully saturated with water vapor at 37 C and 760 mm Hg has a water vapor pressure of 47 mm Hg and an absolute humidity of 43.8 mg/L.

Answer to Question 2

ANS: D
If the absolute humidity is 7.4 mg/L, then the RH is calculated as follows:
RH = 7.4 mg/L  19.4 mg/L  100
RH = 0.38100
RH = 38
