If I have 2.00 moles of solute dissolved into 1.00 L of solvent. What's the molality?

1 Answer

To answer this question we will assume that the solvent is water. The mass of the solvent will be 1.00kg.

NOTE: The density of water is 1g = 1mL

1.00L1x1000mL1Lx1g1mLx1kg1000g= 1.00 kg

To calculate the molality we use the relationship-

molsolutekgsolvent = molality
