Amount in grams equivalent
Amount in volume equivalent
Amount in relative ratios
Amount in moles equivalent
Expert's answer
Amount in moles equivalent

The mole is a unit of measurement used in
chemistry to express amounts of a chemical substance solution and mole is widely
used in chemistry, instead of units of mass or volume, as a convenient way to
express the amounts of reactants and products of chemical reactions. For
example, the chemical equation 2 H2 + O2 → 2 H2O implies that 2 mol of
dihydrogen and 1 mol of dioxygen react to form 2 mol of water. The mole may also
be used to express the number of atoms, ions, or other elementary entities in
some sample.
