Molarity

Molarity is the concentration of a solute in a solution, and learning how to calculate it is a key chemistry concept. This Formula Solver! Series program will walk you through the steps.

The concentration of a compound (or solute) in a solution such as water is called its molarity. Molarity is usually expressed in moles per liter.

Molarity is described by the formula M = ms/Ls where M is molarity, ms is moles of solute, and Ls is liters of solution. This tutorial will show how to use the basic formula to use any two of these to solve for the third.

• Solve for molarity: M = ms/Ls
• Solve for moles of solute: ms = M Ls
• Solve for liters of solution: Ls = ms/M

(Here's a hint: when you get to the end of the solver, change a number and click Next again to see the whole thing recalculated with the new number.)
