For covalent substances, the formula represents the numbers and types of atoms composing a single molecule of the substance; therefore, the formula mass may be correctly referred to as a molecular mass. Consider chloroform (CHCl3), a covalent compound once used as a surgical anesthetic and n...

The molar mass for this compound is computed to be 176.124 g/mol. The given number of moles is a very small fraction of a mole (~10-4 or one-ten thousandth); therefore, we would expect the corresponding mass to be about one-ten thousandth of the molar mass (~0.02 g). Performing th...
The mass of the given compound is assumed to be 100. Hence, the mass percent is taken as the mass (in g) of that element. The mass is then converted into the number of moles. The resultant values are divided by the smallest of the obtained values. Convert all decimal values (...
Scientists use moles to count small objects such as atoms and molecules. Relationship Between Atomic Mass and Moles The periodic table contains entries for all elements. These entries provide the atomic number and atomic mass of each element. For instance, the atomic number of oxygen is 8, and...
