answer: (431,2)

step-by-step explanation:

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

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 =
