This website uses cookies to improve your experience while you navigate through the website. B. CH_3OCH_3. We receieved your request, Stay Tuned as we are going to contact you within 1 Hour. The molecular mass of the NO = 30 g/mol. Molecular formulo - C&HgO. Thanks. Equations 2.10.9 and 2.10.10 describe the right pie chart in Figure \(\PageIndex{1}\). Nitrogen: 2.1714 / 2. . Li2CO3. 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. JavaScript appears to be disabled on this computer. NOTE: Even though mass has units, mass percent is unit-less, and so care needs to be taken to identify what the percent or fraction relates to. .
