How much work is required to move
3.0 coulombs of electric charge a distance of
0.010 meter through a potential difference of
9.0 volts?
(1) 2.7 × 10^3 j (3) 3.0 j
(2) 27 j (4) 3.0 × 10^−2 j

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 =
