Answer:
There are 
moles of bactoX present in a 3.0 μL sample volume that contains 7.512×106 bacterial cells
Explanation:
Given that:
The number of molecules present in one bacterial cell is 
molecules
and the sample contains 
molecules.
Number of moles = number of molecules /Avogadro's number
where;
Avogadro's number = 6.023 × 10²³
Number of moles = 
Number of moles = 
moles
So; moles is present in one bacteria cell
Similarly; the sample contains molecules.
Therefore; the number of moles present in the bactoX is = 
= moles
1. air components change from place to place, while water will just stay the same
2. Water doesn't have nor show individual properties, but air does show that it has it's own property
3. You can separate different gases from air physically, but with water you must pass electricity through it.
Don't take my word for it, this is just what I learned back in middle school.
