Question

What do you mean by gram equivalent mass​

Answer 1

Answer:

Equivalent weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.

Answer 2

HEYA, BUDDY !!

→ 1 g equivalent of a substance is the weight of that amount of a substance which is equivalent to gram equivalent mass.

We can define the equivalent weight of an element as the atomic weight divided by valence electrons in compounds. Its unit is atomic mass unit, the amount of substance in gram is equal to the equivalent weight known as the gram equivalent weight.

→ For example, the hydrogen has atomic weight of 1.008 and the valence electron in hydrogen is 1, so its equivalent weight is 1.008. We can define gram equivalent mass as the mass of one mole of element, ion, molecule divided by their electrons shared or their valences

As we know, For elements that have more than one valency in forming compounds contains more than one equivalent weight.

For example, if iron has a valence of three, then equivalent weight would be 18.615 g/eq. If iron has a valence of two, then equivalent weight would be 27.9225 g/eq.

→ We are calculating the values of equivalent weight using the atomic mass of iron (55.854 g) and the number of electrons shared.

The equivalent weight is used to determine the weight proportion in which is combined to form compounds. We can use equivalent weight in volumetric and gravimetric analysis. We can also use it in polymer chemistry
