One mole of water weights 18 grams, with 2 grams being hydrogen and 16 being oxygen, so the fraction of hydrogen is 2/18 (0.1111) and the fraction oxygen is 16/18 (.8889), and note that the sum of the fractions is 1. The mass percent is calculated by dividing the mass of the element by the molar mass of the compound followed by multiplying it by 100. The mole fraction of each element in a sample is the number of moles of that in a sample divided by the total number of moles in the sample, and this can be determined by the chemical formula, where it is the number of atoms of that element in the formula divided by the total number of atoms in the formula. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula . From the formula we can say that higher the mass of the element, higher will be its mass percentage. Answer (1 of 3): Atomic mass of calcium = 40.078 u, atomic mass of Nitrogen = 14.0067 u and that of oxygen = 15.999 u. Molar mass of Ca(NO3)2 = 40.078+2(14.0067+315.999) = 164.0854 g/mol. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.
