Solute

Key Questions

  • Answer:

    Well, this is a measure of the amount of solute in a given quantity of solution....

    Explanation:

    And there are several ways of expressing concentration...

    "Molarity"="Moles of solute"/"Volume of solution"

    "Molality"="Moles of solute"/"Kilograms of solvent"

    Now at LOW concentrations, generally, "molarity"-="molality"...at higher concentrations (and different temperatures), the values diverge...

    "Percentage by mass"="Mass of solute"/underbrace"Mass of solution"_"mass of solute + mass of solvent"xx100%..

    You have to be able to interpret which concentration is quoted, and which is required...

    There is also chi_"the mole fraction"="Moles of solute"/"Total moles in solution"
