Molality Solution

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

FIRST Step Consider the formula

m = \frac{n}{Mass}

Next Step Substitute values of Variables

∴

m = \frac{3.4483mol}{1.02g}

Next Step Convert Units

∴

m = \frac{3.4483mol}{0.001kg}

Next Step Prepare to Evaluate

∴

m = \frac{3.4483}{0.001}

Next Step Evaluate

∴

m = 3380.6862745098mol/kg

LAST Step Rounding Answer

∴

m = 3380.6863mol/kg
