c. **Conversion From g/mL to Eq/L**. Normality is based on equivalents of solute

per liter of solution.

Example**. **What is the Eq/L concentration of a H2SO4 solution with an S.G. of

1.84 and an assay of 95.0%?

Solution. Express the desired unit of concentration (Eq/L) using the

information given as appropriate factors.

Calculate the GEW of the compound.
