Moles of $Al_2S_3$ Calculated as $0.1398$ mol from $21$ g. Mole ratio Ratio of moles in a compound, $3$ for sulfur. Moles of sulfur Calculated as $0.4194$ mol from $Al_2S_3$. Number of sulfur atoms Total atoms
In general, the lattice thermal expansion for a compound semiconductor can be calculated from a relation containing melting point, mean atomic distance and number of valence electrons for the atoms forming the compound. The mean ionicity for the group compounds forming I 2–IV–VI 3 was found ...
Formal charge = (total number of valence electrons on atom in unbonded state) - (number of non-bonded electrons + number of bonds) Formal charge of atoms in a molecule is different for different resonance structures.Answer and Explanation: ...
For a compound to be saturated, there is one more hydrogen in a molecule when nitrogen is present. Therefore, we add the number of nitrogens (N). This can be seen with C3H9N compared to C3H8. Oxygen and sulfur are not included in the formula because saturation is unaffected by these e...
Atomic Number- the number of protons in the nucleus of an atom of that element Ex: Hydrogen atoms have only one proton in the nucleus, so the atomic. Using Isotope Data to Find a Weighted Average. Each isotope will have two values associated with it. Mass of Isotope...

I guess that you could calculate it by hand, but the result will most probably be poor... In the early days of NMR spectroscopy, integration ratio was obtained by cutting and weighing the paper on which the spectra was printed on. I heard that this was a fairly acurate method......
using a Monte Carlo method; and, using the probability as a performance index, calculating the hole mobility from the number of carriers which exist in the HOMO and the orbitals below the HOMO, or calculating the electron mobility from the number of carriers which exist in the LUMO and the ...
Because of this the QSAR method of approach to a priori calculation of that parameter is of special interest. Traditionally, lipophilicity (log P) is determined as the logarithm of the ratio of the concentrations of the compound when it is distributed in the system octanol--water. The ...
