How do you find exact mass in ChemDraw?
How do you find exact mass in ChemDraw? Chemical Analysis calculationsFormula: ChemDraw shows the chemical formula for the molecule. Exact Mass: ChemDraw calculates the 'Exact Mass' by summing up the molecular weights of the most common isotope of each element. Mol. How do you find the exact molecular weight? The exact mass of an isotopic species (more appropriately, the calculated exact mass) is obtained by summing the masses of the individual isotopes of the molecule. For example, the exact mass of water containing two hydrogen-1 (1H) and one oxygen-16 (16O) is 1.0078 + 1.0078 + 15.9949 = 18.0105 Da. How...
