In a chemical process, an equivalent has been the quantity of one material that people react to (or is equivalent to) an arbitrarily defined quantity of another compound. The mass of an equivalent is equivalent to its weight.

Given:

$1{\text{mole ofMg}}^{2+}$

To compute the value of equivalents.

Each mole has two equivalents for such an ion with a charge of $2+.$Thus the,

${\text{1moleofMg}}^{2+}\text{=2eq}$

Given:

${\text{0.5mole ofH}}^{+}$

To compute the value of equivalents.

Each mole contains a single equivalent for just an ion with a charge of $+.$Therefore,

${\text{0.5moleofH}}^{+}\text{=0.5eq}$

Given:

${\text{4molesofCl}}^{-}$

To compute the value of equivalents.

Every mole uses a single equivalent for an ion with a charge of $-.$Thus,

${\text{4molesofCl}}^{-}\text{=4eq}$

Given:

To compute the value of equivalents.

There's really one equivalent with each mole of an ion with a charge of $-.$Consequently,

${\text{2molesofFe}}^{3+}\text{=6eq}$
