Molality using Molarity Solution

Follow our step by step solution on how to calculate Molality using Molarity?

FIRST Step Consider the formula

m = \frac{Mol \cdot 1000}{ρ \cdot 1000 - Mol \cdot M 1}

Next Step Substitute values of Variables

∴

m = \frac{55.5mol/L \cdot 1000}{997g/L \cdot 1000 - 55.5mol/L \cdot 40g}

Next Step Convert Units

∴

m = \frac{55500mol/m³ \cdot 1000}{997kg/m³ \cdot 1000 - 55500mol/m³ \cdot 0.04kg}

Next Step Prepare to Evaluate

∴

m = \frac{55500 \cdot 1000}{997 \cdot 1000 - 55500 \cdot 0.04}

Next Step Evaluate

∴

m = 55.7912302217576mol/kg

LAST Step Rounding Answer

∴

m = 55.7912mol/kg
