Mary asks…The relative humidity of the air is 61% and temp is 68F. How many molecules of water present in a room 13X10X7?Again, if the relative humidity of the air is 61% and its temperature is 68 degrees F, how many molecules of water are present in a room measuring 13 X 10 X 7ft?
The relative humidity of air equals the ratio of the partial pressure of water in the air to the equilibrium vapor pressure of water at the same temperature, times 100%.
Could you please explain how you came up
