Question
1. What is the relationship between the moles of solute and the mass of solute?
2. Rewrite the molality expression in terms of grams and molecular weight.

Background:

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=((mass of solute)/(molecular weight of solute*kg of solvent)
