The process for converting the volume of an ideal gas to moles is a little different than for mass. You’ll still use a formula, but you do not need the molar mass of the gas for the conversion. mol =volume (L)/22.4 The quantity of a substance in moles is equal to the volume in...
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 now primarily used in the production of the “anti-stick” polymer, Teflon. The molecular ...

How to find molar mass? To find the molar mass: Find the chemical formula for the compound in question. Grab a periodic table. Look up the atomic mass of each atom. Add together the atomic mass of every atom. The result is the molar mass of your substance. How to find the number of...
1023atoms and a mass of 12 grams. In comparison, one mole ofoxygenconsists, by definition, of the same number of atoms as carbon-12, but it has a mass of 15.999 grams. Oxygen, therefore, has a greater mass than carbon. This reasoning also can be applied to molecular or formula ...
One mole of a substance has a mass （equals）_to its relative formula mass in grams, contains （identical) atoms, molecules or formula units.
One mole of a substance is equal to the substance’s 6,022 x 1023 units (such as atoms, molecules, or ions). The 6.022 x 1023 number is known as the number of Avogadro or the constant of Avogadro. For the conversion of mass and number of particles, the definition of the mole can ...
When computing the formula mass of an ionic compound, the average masses of neutral sodium and chlorine atoms were used, rather than the masses for sodium cations and chloride anions. Even though a sodium cation has a slightly smaller mass than a sodium atom (since it is missing an electron...
