About how long does it take for the moon to go from new moon to full moon?

1 month

Explanation:

It takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to full Moon).

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 =

the answer is the last option

explanation:

because in order to know what the molecule is you need to know how many atoms of each element are in the molecule.
