Relative Humidity

Explanation:

Relative humidity is quantity of vapor (water)  in atmosphere at a certain temperature, expressed as % of  amount of the water in the form of vapor needed for saturation of the atmosphere at that temperature.

A measurement of 74% humidity indicates the relative humidity. It is  quantity of vapor in  atmosphere relative to the quantity needed to saturate atmosphere.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
