Molarity is defined as:
C. A measurement of the concentration of a solution
Explanation:
1. Molarity is a unit of concentration that represents the number of moles of solute dissolved in one liter of solution.
2. It is expressed in moles per liter (mol/L) or often denoted as M.
3. The formula for calculating molarity is: Molarity (M) = moles of solute / liters of solution.
For example:
If you have 0.5 moles of salt dissolved in 1 liter of water, the molarity would be 0.5 M (0.5 moles / 1 liter).
Therefore, molarity is a crucial concept in chemistry for determining the strength or concentration of a solution.
