Calculate Equivalent Weight (EW)



Formula

The formula to calculate the equivalent weight (EW) is:

\[ EW = \frac{MW}{\Delta E} \]

Where:

What is Equivalent Weight?

Equivalent weight is the total mass that combines with or is equivalent to one gram of hydrogen. It is the ratio of molecular weight to valence electrons.

Example Calculation

Consider an example where:

Using the formula to calculate the equivalent weight:

\[ EW = \frac{98}{2} = 49 \text{ g} \]

This means that the equivalent weight for this example is 49 g.
