Which statement is from Niels Bohr’s proposed model of the atom? A) All elements are composed of atoms that cannot be divided.
B) All atoms of the same element are exactly alike.
C) Electrons move around the atomic nucleus with specific amounts of energy.
D) Every compound is composed of atoms of different elements, combined in a specific ratio.

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

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

it's 3.2 on edge, i just took the test.
