Quizplus · Accepted Answer

Relative humidity is calculated by taking the actual water vapor in the air (10 g/m³ in this case) and dividing it by the air's capacity to hold water vapor at its current temperature (20 g/m³ at the dewpoint temperature of 20°C). This gives a result of 0.5, which when multiplied by 100 gives a relative humidity of 50%. Therefore, the correct answer is C.

The Relative Humidity Would Be ________% If the Actual Water
