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

i think the answer is 20 %

Answer 2

Answer: 20%

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 ${\text {relative humidity}=\frac{\text {amount of moisture}}{\text {maximum amount of moisture}}\times 100\%$

${\text {relative humidity}=\frac{6g/m^3}{30g/m^3}\times 100\%=20\%$
