Summary Introduction

To determine:

The number of equivalents of ${\text{Mg}}^{2+}$ which are present in a solution that contains $2.50\text{moles}$ of ${\text{Mg}}^{2+}$.

Introduction:

The equivalents of ${\text{Mg}}^{2+}$ present in a solution that contains $2.50\text{mol}$ of ${\text{Mg}}^{2+}$ is calculated by the formula,

$\text{Number}\text{of}\text{equivalent}=\text{Number}\text{of}\text{given}\text{moles}\times \frac{\text{Positive}\text{charge}\text{on}\text{the}\text{given}\text{ion}}{1\text{mol}\text{of}\text{the}\text{given}\text{ion}}$

The number of equivalents is defined as the number of moles multiplied by the positive charge on the given ion per mole of the ion.
