Calculate the normality of each of the following solutions.

c. 5.3 x 10^{-2} *M* H_{3}PO_{4}

What is the equivalent mass for each of the acids or bases listed above?

We’re being asked to calculate for the normality of the H_{3}PO_{4} solution and determine the equivalent mass of the acid.

**Normality (N)** represents the number of equivalents per liter of solution.

$\overline{){\mathbf{N}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{equivalents}\mathbf{}\mathbf{of}\mathbf{}\mathbf{solution}}{\mathbf{L}\mathbf{}\mathbf{solution}}}$

$\overline{){\mathbf{equivalents}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{\mathbf{n}}{\mathbf{\times}}{\mathbf{moles}}}$
