By entering known data such as the molar mass of the dissolved substance and the density of the solution, the Free Concentration Calculator transforms molarity to percentage concentration or vice versa. If the percentage concentration is known, this tool can also calculate the mass of the substance per 100 g of H2O. Simply enter the density of the solution, molar mass, and molarity of the substance into the input fields and press the calculate button to quickly obtain the result.

What is Concentration?

Concentration is a term that describes the composition of a solution, most typically a water solution, although it can also be applied to any mixture. In other words, it's the mass, moles, or other units of a constituent divided by the total mass or volume of a solution. Two instances of mathematical descriptions are molarity and mass percent concentration. Furthermore, the solute-to-solvent ratio in a solution can be utilised to define a solution. To calculate molarity, use a molarity calculator.

The terms concentrated and dilute can be used to characterise the solution qualitatively. A concentrated solution has a larger concentration of solute, whereas a dilute solution has a lower concentration of the dissolved substance. You can use the solution dilution calculator to compute the concentration of a diluted solution if you know the concentration of a solution before diluting it.

Mass Percentage Concentration Formula

The mass of the solute divided by the entire mass of the solution into 100 equals the mass percent concentration (wt%). wt% = m1/m2 x 100%

  • Where, m₁ = mass of the solute
  • m₂ = mass of the solution

Percentage Concentration Formula

The following is the equation for calculating the percentage concentration from the molarity

  • wt% = Molarity * 100% * Molar Mass/Density
  • Molarity = wt% * Density/(Molar Mass * 100%)
  • Molar Mass = wt% * Density/(Molarity * 100%)

The amount of substance per 100g of water is m = wt% * 100/(100 - wt%)

How to Convert Molarity to Percentage Concentration?

The steps for calculating the percentage concentration of a solution using the molarity and molar mass are as follows. Go over these rules and make sure you follow them to the letter.

  • Step 1: Calculate the solution's molar mass, molarity, and density.
  • Step 2: Multiply the molarity by the molar mass.
  • Step 3: Multiply the result by 100 percent once more.
  • Step 4: To determine the appropriate concentration, divide the value by the density.

FAQ’s on Concentration Calculator

1. What is a concentration calculator?

With a known molar mass of dissolved substance and density of the solution, the concentration calculator converts molarity to percentage concentration (or vice versa). If the percentage concentration is known, you may also compute the mass of the material per 100 g of water.

2. What is the procedure for converting concentration to molar concentration?

The concentration formula: Simply divide the total moles of solute by the total volume of the solution in litres to determine the molar concentration of a solution.

3. How to dilute a molar concentration?

Dilution is the process of lowering a solution's concentration. The amount of solute dissolved in a given volume of solution is referred to as concentration. By adding more solvent to the stock solution, a solution can be diluted. c1V1 = c2V2 is the dilution equation.

4. How can you find out what a solution's final concentration is?

In general, the Final Concentration Calculator Calculates the quantity of solute in both original mixtures, add them together, then divide by the total amount of solution to find this out. If you wish to convert it to a percentage, multiply by 100.
