How do you calculate mole?
The mole represents a quantity of substance, but relates to the number of atoms or molecules rather than mass or volume. Specifically, 1 mole represents 6.022 x 10^23 atoms or molecules of substance. You calculate the number of moles by dividing the mass of substance by the substance’s atomic or molecular weight.
How do you calculate molecular mass?
Molecular mass may be calculated by taking the atomic mass of each element present and multiplying it by the number of atoms of that element in the molecular formula. Then, the number of atoms of each element is added together.
How do you calculate the number of moles in a compound?
The number of moles you have of a compound can be calculated by dividing the number of grams of the compound by the molecular mass of the compound. The formula looks like this: moles = grams of compound/molar mass of compound. 2. Plug your numbers into the formula.
How do you calculate chemical weight?
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
