Final answer:
Concentration is a measure of the amount of solute dissolved in a given volume of liquid. The solubility of a substance is the amount required to form a saturated solution. Making a solution of known concentration involves dissolving a measured amount of solute in enough solvent.
Step-by-step explanation:
Concentration is a measure of the amount of solute that is dissolved in a given volume of liquid. It is measured in mol-dm-³. The solubility of a substance is the amount of that substance that is required to form a saturated solution in a given amount of solvent at a specified temperature. Making a solution of known concentration involves dissolving a measured amount of solute in enough solvent to make the desired volume of the solution.
