The air that we breathe contains oxygen, water, nitrogen, dust, pollen, pollution, and other materials. we can clean air using an air filter. air is most likely a a compound an element a mixture a molecule

Answer :A molecule

Explanation:

Its a compound because a molecule is just a single type of atom, and like you said, air is made up of many types of atoms or things.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
