Answer- The above question is from the chapter 'Some Basic Concepts of Chemistry'.

Equivalent Weight- It is the mass of one gram equivalent i.e. the mass of a particular element which can combine/displace 1 gram of hydrogen or 8 grams of oxygen or 35.5 grams of chlorine.

Some important formulae:

1. Equivalent Weight of an Acid = Molecular Weight ÷ Basicity

2. Equivalent Weight of a Base = Molecular Weight ÷ Acidity

3. Equivalent Weight of a Salt = Molecular Weight ÷ Total Cation/Anion Charge

4. Equivalent Weight of an Ion (In Redox Reactions) = Molecular Weight ÷ Change in Oxidation State

Given question: The equivalent weight of an acid is equal to

(1) Molecular weight/basicity

(2) Molecular weight × basicity

(3) Molecular weight × acidity

(4) Molecular weight/acidity​

Answer: (1) Molecular weight/basicity
