## Molality Solution

STEP 0: Pre-Calculation Summary
Formula Used
molality = Number of Moles of Solute/Solvent Present in Solution per Kg
m = n/Mass
This formula uses 2 Variables
Variables Used
Number of Moles of Solute - The number of Moles of Solute is the total number of representative particles present in the solute. (Measured in Mole)
Solvent Present in Solution per Kg - Solvent Present in Solution per Kg is the amount of solvent present in the solution in terms of kgs. (Measured in Kilogram)
STEP 1: Convert Input(s) to Base Unit
Number of Moles of Solute: 3.4483 Mole --> 3.4483 Mole No Conversion Required
Solvent Present in Solution per Kg: 1.02 Kilogram --> 1.02 Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
m = n/Mass --> 3.4483/1.02
Evaluating ... ...
m = 3.3806862745098
STEP 3: Convert Result to Output's Unit
