Dilution Volume Calculator | Online
In labs, dilute solutions are made by diluting a certain volume of concentrated solution. Distilled water is added to dilute the solution. In this case, we need to calculate volume of concentrated solution and volume of distilled water. In this online calculator, you can simply do the calculations and get answers in few seconds.
Example: Preparing a 0.1 mol dm-3 HCl 500 cm3 solution from 1 mol dm-3 concentrated HCl solution.
Online calculator for calculate required volume of distilled water and required volume of concentrated solution
You can calculate followings from this calculator.
- Required volume from the concentrated solution to prepare a dilute solution
- Required Volume of Distilled Water to prepare the final solution
Answer
Example problem for calculating concentrated solution and volume of distilled water
You may need to prepare a 0.1 mol dm-3 HCl 500 cm3 solution from 1 mol dm-3 concentrated HCl solution. Calculate required volume from 1 mol dm-3 concentrated HCl solution and required volume of distilled water.
Calculation of required volume of concentrated HCl solution
HCl amount in final solution is given by concentrated HCl solution. Therefore,
- HCl amount given by concentrated HCl solution = HCl amount in final solution
- C1V1 = C2V2
- C1 = concentration of concentrated HCl solution
- V1 = volume of concentrated HCl solution
- C2 = concentration of final solution
- V2 = volume of final solution
- 1 * V1 = 0.1 * 500
- V1 = 50 cm3
Because, C1, C2 and V2 are given as data, we can calculate unknown data of V1. So, now we know the required volume of concentrated HCl solution.
Calculation of volume of distilled water
Final volume is the summation of volume of concentrated HCl solution and volume of distilled water. Therfore, volume of distilled water is calculated from following equation.
- volume of distilled water = volume of final solution - volume of concentrated HCl solution
- volume of distilled water = 500 - 50
- volume of distilled water = 450 cm3
