The device shows the relative humidity at 22 degrees celsius. What's the water vapor density if the maximum water vapor in air at this temperature is 20 gram/cubic meter

11.6 g/m³

Explanation:

The complete question is,

The device shows the relative humidity at 22 degrees celsius. What's the water vapor density if the maximum water vapor in air at this temperature is 20 gram/cubic meter? a device showing that at 22 degrees celsius the relative humidity is 58%.

Solution:

saturation of water in air is showed by the relative humidity. As it is 58% and not 100%. Lets scale density that we have, if humidity is 100%.

density is 20 gram/m³ when the humidity is 100%

When humidity is 58%

0.58 x 20 = 11.6 g/m³

Therefore, density is 11.6g/m³
