Explanation:

caca

density =  0.791 g/cm^3

specific weight =  775 g /(cm^2 s^2)

Explanation:

Recall that density is defined as: Mas / Volume

Then, in our case:  density = 500 g / 632 cm^3 = 0.791 g/cm^3

Recall that the specific weight is defined as the product of the density times the local acceleration of gravity, so in our case:

Specific weight = 0.791 * 980 = 775 g /(cm^2 s^2)

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 =
