Solution Concentration Calculator

Percent concentration always depends on the basis you state — mass over mass, mass over volume, or volume over volume.

g for w/w and w/v; mL for v/v.

g for w/w; mL for w/v and v/v. Enter the whole solution, not just the solvent.

Calculation Breakdown

  1. Divide the solute by the whole solution5 g ÷ 100 g = 0.050000fraction = solute / solution
  2. Scale to a percentage0.050000 × 100 = 5%% = fraction × 100

What Is the Solution Concentration Calculator?

A concentration calculator works out the percentage strength of a solution.

How Does the Solution Concentration Calculator Work?

It divides the solute by the whole solution on the chosen basis and scales to percent, ppm and ppb.

Solution Concentration Calculator Formula & Variables

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

%=solutesolution×100\% = \dfrac{\text{solute}}{\text{solution}} \times 100

The solute is divided by the whole solution on the chosen basis, then scaled to a percentage.

How to Use the Solution Concentration Calculator

  1. Choose the basis and enter the solute and total solution amounts.

Step-by-Step Example Calculation

5 g in 100 g

Input Values:

basis:ww
soluteAmount:5
solutionAmount:100
Worked Steps: That is a 5% w/w solution, or 50,000 ppm.

Understanding Your Result

The result shows the percentage, ppm and ppb for the chosen basis.

Factors That Affect the Result

  • The solute amount and the total solution amount determine the percentage.

When Should You Use This Calculator?

  • Use it for preparing and checking laboratory and medical solutions.

Assumptions & Limitations

  • The basis must be stated; w/v and v/v assume ideal mixing.
