To calculate the number of moles of a compound you have on hand, you divide the mass by the mass of one mole of the compound, which you can calculate from the periodic table.Using the Mole Fraction Equation The mole fraction formula is particularly easy to understand and use if you ...
Using these numbers, we can find the number of moles of each element in the 100-gram sample. Divide the number of grams of each element in the sample by the atomic weight of the element to find the number of moles. moles C = 40.00 g x 1 mol C/12.01 g/mol C = 3.33 moles C mo...

First of all, convert the masses to the number of moles of each compound, and use theperiodic tablefor the atomic masses of the elements. Besides, the atomic mass unit of carbon is 12.0 amu (rounding to one decimal place) and of chlorine, the amu is 35.5. So, one mole o...
Equivalent weight, on the other hand, is the portion of the compound's molecular weight associated with each valence electron. For a compound, equivalent weight takes the molecular weight and divides it by the net positive valence. What is the formula for equivalent weight? The Equivalent Weight...
