Molarity using Molality Solution

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

FIRST Step Consider the formula

Mol = \frac{ρ}{(\frac{1}{m}) + (\frac{M solute}{1000})}

Next Step Substitute values of Variables

∴

Mol = \frac{997g/L}{(\frac{1}{0.034mol/kg}) + (\frac{35g}{1000})}

Next Step Convert Units

∴

Mol = \frac{997kg/m³}{(\frac{1}{0.034mol/kg}) + (\frac{0.035kg}{1000})}

Next Step Prepare to Evaluate

∴

Mol = \frac{997}{(\frac{1}{0.034}) + (\frac{0.035}{1000})}

Next Step Evaluate

∴

Mol = 33.897959661428mol/m³

Next Step Convert to Output's Unit

∴

Mol = 0.033897959661428mol/L

LAST Step Rounding Answer

∴

Mol = 0.0339mol/L
