Normality Calculator

Normality Calculator estimates the normality (N) of a solution based on the mass of solute, equivalent weight, and volume of solution, with a detailed breakdown and step-by-step calculations.

Solute:

Molar Mass (g/mol, e.g., 40):

Equivalents per Mole (e.g., 1):

Mass of Solute (g, e.g., 40):

Volume of Solution (L, e.g., 1):

Time Zone:

Normality Calculator computes the normality (N) of a solution, defined as gram-equivalents of solute per liter of solution, using mass of solute, equivalent weight, and solution volume.

Enter values to calculate normality:

Mass of Solute (g):

Equivalent Weight (g/equiv):

Volume of Solution (L):

Methodology Used in Normality Calculator

The calculator computes normality (N) using:

1. Normality: \\( N = \frac{\text{Mass of Solute}}{\text{Equivalent Weight} \cdot \text{Volume of Solution}} \\)

Where:

\\( \text{Mass of Solute} \\): Mass of the solute in grams (g)
\\( \text{Equivalent Weight} \\): Mass per equivalent in grams per equivalent (g/equiv)
\\( \text{Volume of Solution} \\): Volume of the solution in liters (L)
\\( N \\): Normality in equivalents per liter (equiv/L)

Normality measures the concentration of reactive units in a solution.

Example Calculation

Sample Input

Mass of Solute = 5 g, Equivalent Weight = 36.5 g/equiv (e.g., HCl), Volume of Solution = 1 L

Step 1: Normality: \\( N = \frac{\text{Mass of Solute}}{\text{Equivalent Weight} \cdot \text{Volume of Solution}} = \frac{5}{36.5 \cdot 1} \approx 0.14 \, \text{equiv/L} \\)

Result: Normality = 0.14 equiv/L.
