Question

The maximum water vapor that air can hold at 30°C is about 30 grams/cubic meter. If the humidity of the air is currently 6 grams/cubic meter at the same temperature, the relative humidity is %.

Answer 1

Answer: 20%

Step-by-step explanation: Relative humidity is the ratio of amount of moisture in the air to the maximum amount of moisture that could exist in the air at a specific temperature.

Thus
`{\text {relative humidity}=\frac{\text {amount of moisture}}{\text {maximum amount of moisture}}* 100\%`

`{\text {relative humidity}=(6g/m^3)/(30g/m^3)* 100\%=20\%`
