Molarity is defined as:

Molarity is defined as:

• A. (moles of solute / gram of solvent)
• B. (moles of solvent / L of solution)
• C. (moles of solute / L of solution)
• D. (grams of solute / L of solution)

Answer: (C)

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. This expresses how much dissolved substance is present in a given total volume, using moles to reflect a count of particles. So the defining expression is moles of solute divided by liters of solution. For example, dissolving 1 mole of solute so that the total solution volume is 1 liter gives a concentration of 1 M. The other options mix mass or solvent-based quantities with volume, which do not describe molarity.
