Molality using Molarity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Molality = (Molarity*1000)/(Density of water*1000-Molarity*Molar Mass of Solute)
m = (Mol*1000)/(ρ*1000-Mol*M₁)
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.
Molarity - (Measured in Mole per Cubic Meter) - Molarity of a given solution is defined as the total number of moles of solute per litre of solution.
Density of water - (Measured in Kilogram per Cubic Meter) - Density of Water is the weight of the water per its unit volume, which depends on the temperature.
Molar Mass of Solute - (Measured in Kilogram) - The Molar Mass of Solute is the molar mass of the substance dissolved in the solution.

STEP 1: Convert Input(s) to Base Unit

Molarity: 55.5 Mole per Liter --> 55500 Mole per Cubic Meter (Check conversion here)
Density of water: 997 Gram per Liter --> 997 Kilogram per Cubic Meter (Check conversion here)
Molar Mass of Solute: 40 Gram --> 0.04 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

m = (Mol*1000)/(ρ*1000-Mol*M₁) --> (55500*1000)/(997*1000-55500*0.04)

Evaluating ... ...

m = 55.7912302217576

STEP 3: Convert Result to Output's Unit

55.7912302217576 Mole per Kilogram --> No Conversion Required

FINAL ANSWER

55.7912302217576 ≈ 55.79123 Mole per Kilogram <-- Molality
