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 =
