Molality given Ionic Activity and Activity Coefficient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Molality = Ionic Activity/Activity Coefficient
m = a/γ
This formula uses 3 Variables

Variables Used

Molality - (Measured in Mole per Kilogram) - Molality is defined as the total number of moles of solute per kilograms of solvent present in the solution.
Ionic Activity - (Measured in Mole per Kilogram) - The Ionic activity is the measure of the effective concentration of a molecule or ionic species.
Activity Coefficient - Activity coefficient is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances.

STEP 1: Convert Input(s) to Base Unit

Ionic Activity: 0.54 Mole per Kilogram --> 0.54 Mole per Kilogram No Conversion Required
Activity Coefficient: 1.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

What is Ionic activity?

The deviation from ideality of a solute particle-(In this case solute behaves as a
completely dissociated system, that is strong electrolyte) can be expressed in terms of solute activity, denoted by the letter ‘a’. Activity is defined as a measure of the effective concentration of a molecule or ionic species. Activity depends on the temperature, pressure and composition of the mixture of species. Activity of a solute depends on its concentration, being proportional to concentration at sufficient dilution.

How to Calculate Molality given Ionic Activity and Activity Coefficient?

Molality given Ionic Activity and Activity Coefficient calculator uses Molality = Ionic Activity/Activity Coefficient to calculate the Molality, The Molality given Ionic Activity and Activity Coefficient formula is defined as the ratio of the ionic activity to the activity coefficient of the electrolyte. Molality is denoted by m symbol.
