1 M — Molarity

Calculation Breakdown

  1. Moles of soluten = mass ÷ molar massn=mMn = \dfrac{m}{M}
  2. MolarityM = moles ÷ volume (L)M=nVM = \dfrac{n}{V}

What Is the Molarity Calculator?

Molarity expresses concentration as moles of solute per litre of solution.

How Does the Molarity Calculator Work?

It converts mass to moles if needed, then divides by the solution volume.

Molarity Calculator Formula & Variables

The core mathematical equation utilized by this calculator is expressed as:

M=nVM = \dfrac{n}{V}

Molarity divides the moles of solute by the volume of the whole solution in litres.

How to Use the Molarity Calculator

  1. Choose the solute input, enter the solution volume and read the molarity.

Step-by-Step Example Calculation

58.44 g NaCl in 1 L

Input Values:

input:mass
volumeL:1
mass:58.44
molarMass:58.44
Worked Steps: That is a 1 mol/L solution.

Understanding Your Result

The result is the molarity, with moles and volume shown.

Factors That Affect the Result

  • Solute amount and solution volume set the molarity.

When Should You Use This Calculator?

  • Use it for preparing solutions and for stoichiometry in liquid phase.

Assumptions & Limitations

  • Assumes the solution volume is measured at the working temperature.
