How much heat energy is required to raise 2 kilograms of water from 20 degrees celsius to 45 degrees celsius? the specific heat of water is 4,184 J/Kg c. please help with work showed

i believe the answer is a hope it and is correct

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 =
