Finding the mass percent requires the molar mass of the elements in the compound in grams/mole or the number of grams used to make a solution. Which of these compounds has the largest percentage by mass of nitrogen? The molar mass of the N2 molecule is therefore 28.02 g/mol. 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. Mass percent composition is also known percent by weight. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Finding molar mass starts with units of grams per mole (g/mol).
