There are about 1.27 × 10^23 molecules present in 13.5 g of SO2.
<h3>What are molecules?</h3>
A molecule is the simplest part of a compound that have independent existence.
Number of moles of sulfur dioxide = 13.5 g/64 g/mol = 0.211 moles
If 1 mole of SO2 contains 6.02 × 10^23 molecules
0.211 moles of SO2 contains 0.211 moles × 6.02 × 10^23 molecules/1 mole
= 1.27 × 10^23 molecules
32 g of sulfur contains 6.02 × 10^23 atoms
x g of sulfur contains 2.23 x 10^23
x = 32 × 2.23 x 10^23 /6.02 × 10^23
x = 11.85 g
6.02 × 10^23 formula units has a mass of AgF = 127 g
x formula units has a mass of = 42.15 g
x = 6.02 × 10^23 × 42.15/127
x = 2 × 10^23 formula units
6.02 × 10^23 formula units of Fe2O3 has a mass of 160 g
8.83 x 10^23 formula units of Fe2O3 has a mass of 8.83 x 10^23 x 160 g/6.02 × 10^23
x = 235 g

Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.
According to Bohr's theory, it is difficult to locate electron or cannot be located in a definite region. Electron has to be found in an orbit and nowhere else. When the probability of finding an electron in a given spherical shell around the nucleus is plotted the distance of the electron from the nucleus for the hydrogen atom, the graph indicates that the probability of finding the electron increases as the distance between the electron and the nucleus decreases
Bohr claimed that electrons a entities had only probabilities if they weren't observed. While Einstein argued that they had independent reality.
But in wave mechanics Model, there is a slight chance of knowing the location of the electron.
Heisenberg uncertainty principle also claim the possibility of knowing the position of electron. Albert Einstein also claim that; to determine the position of an electron to an accurate extent, you would have to compromise your ability to know it's momentum. This inaccuracy will eventually affect the measurement of momentum which will be extremely uncertain.
Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.
