6. The concentration of a solution is : a)The amount of solvent needed to fully dissolve a solute b)The measurement of how large
Maurinko [17]

Answer:

Option c) The measurement of how much solute can be dissolved in a liter of solvent.

Explanation:

The concentration of a solution can be defined as the amount of solute in 1 litre of the solvent i.e how much of the solute that can dissolve in a litre of the solvent. Mathematically, it can be written as:

Concentration = mole of solute / Volume of solvent

Thus, the unit for the concentration is mole per litre (mol/L)

From the above illustration, we thus say that the concentration of a solution is a measure of how much solute can be dissolved in a liter of solvent.
