At 96° F the saturation density of air is 0.04 kg/m3. If the weather report says the relative humidity is 90 % when the temperature is 96°F, the humidity is

The value is  

Explanation:

From the question we are told that

   The saturation density of air is

   The temperature for this saturation density to occur  

    The relative humidity at this temperature is  

Generally the relative humidity is mathematically represented as

Here H represents humidity

=>

=>  

=>  

increases it

e/c, where e is its total energy
