One mole of a substance is defined as 6.02 × 1023individual particles (atoms or molecules) of that substance. (This happens to be the exact number of atoms in 12 grams of carbon.) As you move from left to right and downward on the periodic table, the mass of one mole of a given e...
from Chapter 9/ Lesson 6 163K How to calculate the theoretical yield? Learn the definition and formula of percent yield. Use the theoretical yield equation to calculate theoretical yield. Related to this Question Calculate the mass of calcium carbonate precipitate that ...
The oxidation reaction of a compound is the same as the combustion of that compound with O2 gas. If the exact chemical formula and amount of the compound are known, then the oxygen required can be obtained from the balanced chemical equation ...
In these specific cases, mean deviation of semi-classically evaluated electron energy levels of atomic orbitals and energy difference of molecular orbitals from corresponding atomic ionization potentials and molecular term are about a few percent. As for the full practical realization of the introduced ...
If you're subtracting the 2 yields, you're using the percent error formula instead. If you get wildly different results, check your units. If your actual yield is different from your theoretical yield by an order of magnitude or more, you probably used the wrong units at some point in ...
