Number of gram equivalent of solute dissolved in one litre of solution is called its

ANS:A - normally

Normally" is not a term typically used in the context of chemistry when discussing the concentration of a solution. It seems like it might be a typo or a misunderstanding. If you meant to ask about "normality," then normality is a measure of concentration that relates the number of equivalents of a substance to the volume of solution in liters. An equivalent is a measure of the reactive capacity of a compound. For example, in acid-base reactions, one equivalent of an acid is the amount that can donate one mole of protons (H⁺ ions), and one equivalent of a base is the amount that can accept one mole of protons. Normality (N) is calculated using the formula: 𝑁=Number of equivalents of soluteVolume of solution in litersN=Volume of solution in litersNumber of equivalents of solute​ So, normality represents the concentration of reactive species in a solution. It's particularly useful in acid-base and redox reactions where the number of equivalents of reactants is crucial.
