0.1m moles of solute particles are present in 1 L of each of the following aqueous solutions.
The number of moles of solute = mass of solute ÷ molar mass of solute, where mass is measured in grams and molar mass (defined as the mass of one mole of a substance in grams) is measured in g/mol
Molality is defined as moles of solute per kilogram of solvent. Molality = mass of solvent (in kg) moles of solute = molecular weight of solute × mass of solvent (in kg) mass of solute.
