Using steam tables, calculate the fugacity and fugacity coefficient of: (a) Superheated steam at 50.0 MPa and 500 ◦C. (b) Saturated liquid water at 200 ◦C. (c) Compressed liquid water at 20.0 MPa and 200 ◦C

unlike poles attract

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 =
