The amount of substances that completely react with each other in the reaction is called equivalent weight in chemistry. While answering the question, what is equivalent weight? you should keep in mind that its definition depends on the two factors; the molar mass and valency factor of the compound.

Formula Weight (FW) A formula weight is the sum of the atomic weights for the atoms in a chemical formula. So, the formula weight of calcium chloride, CaCl2, would be. Ca: 1(40.1 amu) + Cl: 2(35.5 amu) 111.1 amu. Formula weights are generally reported for ionic compounds.
The equivalent weight of a substance involved in a neutralization (acid/base) reaction is defined as that weight which reacts with or contributes 1 gram formula weight of hydrogen ion in that reaction. This is discussed at some length in your textbook.
