Question

what are equivalent grams of solute in normality ?? And what is the significance of normality ?? And also plzzz explain Formality.

Answer 1

equivalent gram mass= given mass/equivalent mass.
normality gives equivalent per liter volume. Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. Gram equivalent weight is the measure of the reactive capacity of a molecule

Formality of a solution may be defined as the number of gram formula masses of the ionic solute dissolved per litre of the solution. It is represented by . Commonly, the term formality is used to express the concentration of the ionic solids which do not exist as molecules but exist as network of ions.
