Mass can be defined as a quantitative measure of an object's resistance to the change of its speed. . Scientifically speaking, mass IS different than weight, which is the measure of a planet’s gravitational force on an object. Use . the coefficients to predict the amount of reactant consumed or product formed. The ratio of the coefficients is a ratio of the moles taking part in a reaction.. Reactants (on the left of the arrow) are consumed.
