Molality using Mole Fraction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Molality = (Mole Fraction of Solute*1000)/(Mole Fraction of Solvent*Molar Mass of Solvent)
m = (x_solute*1000)/(x₂*M_solvent)
This formula uses 4 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.
Mole Fraction of Solute - Mole Fraction of Solute is the ration of the number of moles of the solute to the total number of moles of the solute and solvent.
Mole Fraction of Solvent - Mole Fraction of Solvent is the ratio of the number of moles of solvent to the total number of moles of solute and solvent.
Molar Mass of Solvent - (Measured in Kilogram) - The Molar Mass of Solvent is the molar mass of the medium in which the solute is dissolved.

STEP 1: Convert Input(s) to Base Unit

Mole Fraction of Solute: 1.4 --> No Conversion Required
Mole Fraction of Solvent: 0.19 --> No Conversion Required
Molar Mass of Solvent: 25 Gram --> 0.025 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

m = (x_solute*1000)/(x₂*M_solvent) --> (1.4*1000)/(0.19*0.025)

Evaluating ... ...

m = 294736.842105263

STEP 3: Convert Result to Output's Unit

294736.842105263 Mole per Kilogram --> No Conversion Required

FINAL ANSWER

294736.842105263 ≈ 294736.8 Mole per Kilogram <-- Molality

What is stoichiometry?

Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers.
