Ajeweler wants to melt a ring. assume the ring is pure silver and has a mass of 33 grams and the initial temperature of the ring is 58 degrees. how much energy is required to melt the ring? (use the attached table for needed constants)
2,913.9 j
3,939.87 j
9,767.67 j
6,853.77 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 =
