At a room temperature of 22° C, air has the capacity to hold 19.4 mg/L of water vapor. If the absolute humidity in the air is 7.4 mg/L, then what is the relative humidity (RH)?
a. 45%
b. 58%
c. 70%
d. 38%
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 = 0.38?100
%RH = 38%
