Equivalent Mass Calculator

Formula

To calculate the Equivalent Mass:

\[ Meq = \frac{MM}{HG} \]

Where:

\(Meq\) is the Equivalent Mass (g/mol/group)
\(MM\) is the molar mass (g/mol)
\(HG\) is the number of hydroxyl groups

Equivalent Mass Definition

Equivalent mass refers to the mass of a substance that combines with or displaces a fixed amount of another substance. In this context, it is calculated by dividing the molar mass by the number of hydroxyl groups.

Example Calculation 1

Let's assume the following values:

Molar Mass (\(MM\)) = 180 g/mol
Number of Hydroxyl Groups (\(HG\)) = 3

Using the formula:

Step 1: Divide the molar mass by the number of hydroxyl groups:

\[ Meq = \frac{180}{3} = 60 \text{ g/mol/group} \]

Example Calculation 2

Let's assume the following values:

Molar Mass (\(MM\)) = 98 g/mol
Number of Hydroxyl Groups (\(HG\)) = 2

Using the formula:

Step 1: Divide the molar mass by the number of hydroxyl groups:

\[ Meq = \frac{98}{2} = 49 \text{ g/mol/group} \]
