The amount of inertia an object has depends on its mass. The more mass an object has, the more inertia. Inertia is an object's tendency to do nothing.
Wait so we write the essay?
Bohr's theory states that the motion of the electron (particle) around the nucleus is very much similar to motion of the planets around the sun in the solar system. Both in the mathematical and physical sense.
The Bohr's Atomic theory only explains the motion of the electrons in discrete atomic orbitals that are predicted by the Bohr's equation.
It strictly implies that the electron only exists in these discreet orbitals and fails to explain anything about the nature of the electron in between the discrete orbitals.
The modern atomic theory does not share this limitation as it does not impose the electron to only occupy the discrete orbitals and neither does it impose particle nature upon the electron.
In the modern theory does not focus on describing the motion of the electron around the orbital but rather the probability of finding an electron around the nucleus. The modern atomic orbitals or electron clouds are the regions in which the probability of finding the electron is the highest when the wave function collapses. The Schrödinger's wave equation explains the evolution of the wave function in time. Hence enabling us to predict the future possible locations of the electron but never the exact location as that is impossible due to the Heisenberg's Uncertainty principle.

2.66 molecules of ammonia are produced
Explanation:
We have bellow the chemical reaction between nitrogen (N₂) and hydrogen (H₂) which produce ammonia (NH₃):
N₂ + 3 H₂ → 2 NH₃
From the chemical reaction we see that 1 molecule of nitrogen reacts with 3 molecules of hydrogen, so 4 molecules of nitrogen will react with 12 molecules of hydrogen but we only have 4 molecules of hydrogen available, so the limiting reactant will the hydrogen. Knowing this we devise the following reasoning:
if 3 molecules of hydrogen produces 2 molecules of ammonia
then 4 molecules of hydrogen produces X molecules of ammonia
X = (4 × 2) / 3 = 2.66 molecules of ammonia
However it does not make sense to produce half a molecule of something (you can not do this in the real world), the problem will make sense if you talk about the number of moles of each substance, because in 1 mole of substance you have 6.022 × 10²³ molecules.
You may find in the attached picture the drawing of the molecules.
