Answer:
1. the solution tells you how much solute has been dissolved in the solvent. ... There are many different units of concentration. The standard unit of concentration in chemistry is molarity,Molarity is defined as moles of solute per liters of solution.
2. Often, a worker will need to change the concentration of a solution by changing the amount of solvent. Dilution is the addition of solvent, which decreases the concentration of the solute in the solution. Concentration is the removal of solvent, which increases the concentration of the solute in the solution.
