Problem Statement

What is molarity and how do you calculate it?

Step-by-Step Explanation

Molarity measures moles of solute per liter of solution.

  1. Identify what the question is asking. In General Chemistry, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
  2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
  3. Work one step at a time and keep units, signs, and restrictions visible.
  4. Check whether the answer makes sense in the original context.

Key Formula

M=moles soluteliters solutionM=\frac{\text{moles solute}}{\text{liters solution}}

Final Answer

Molarity measures moles of solute per liter of solution. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
