What is the name of this atom's model that is commonly used by Chemistry students to show the basic structure of an atom?
"Plum Pudding model" by JJ Thomson
"Bohr's Model" by Neils Bohr
"Rutherford's Model" by Ernest Rutheforf

It is the "Bhor's Model"

Explanation:

Nearly two-thirds of the students ranked the electron cloud and Bohr-model as their two most preferred representations. Students invoked ideas from classical mechanics to interpret the electron cloud model and used probabilistic language to describe the Bohr model of the atom.

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
