- Get the moles:
- Get the molar mass:
- Following step three, we obtain: 2.50 moles x 122.550 g/mole = 306.375 grams.
What is the formula to calculate molar mass?
However, the SI unit for molar mass is kgmol -1 (or kg/mol). The molar mass can be calculated using the following equation. Molar Mass = Mass of the Substance (Kg)/Amount of Substance (Mol) Mole or mol is the unit used to measure the amount of a substance.
What is the mass percent of iron in Fe2O3?
mass of iron in Fe2O3 = 2(55.8) = 111.6 grams. Mass percent of iron can be calculated by dividing the mass of iron by the mass of the compound and then multiplying the quotient by 100 to get the percentage. Based on this: mass % of iron = (111.6/159.6)*100 = 69.92%.
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 mass of a mole?
Answer Wiki. In order to calculate the mass of one mole of a molecule, we must simply find the atomic weight of each atom in that molecule, multiply each by the number of times it appears, and add them all together.
