The Weight Volume Percent Calculator is a valuable tool used in chemistry to determine the concentration of a solution. It calculates the weight volume percent, which represents the amount of solute present in a given volume of solution, expressed as a percentage. This calculation is essential for various applications in chemistry, such as preparing solutions of known concentrations for experiments or analyzing the concentration of substances in solutions.
Formula of Weight Volume Percent Calculator
The formula for calculating the weight volume percent (w/v%) is straightforward:
w/v% = (weight of solute in grams) / (volume of solution in milliliters) * 100
To utilize this formula effectively, follow these steps:
- Identify the Solute and Solvent: The solute is the substance being dissolved, while the solvent is the substance doing the dissolving.
- Gather the Data: Obtain the weight of the solute in grams and the volume of the solution in milliliters.
- Plug the Values into the Formula: Substitute the weight and volume into the equation.
- Calculate: Multiply the result by 100 to express the answer as a percentage.
General Terms Table
Here's a helpful table of general terms related to the Weight Percent Calculator:
| Solute Weight (g) | Solution Volume (mL) | w/v% |
|---|---|---|
| 5 | 100 | 5 |
| 10 | 200 | 5 |
| 15 | 300 | 5 |
| 20 | 100 | 20 |
| 25 | 200 | 12.5 |
| 30 | 300 | 10 |
Example of Weight Volume Percent Calculator
Let's consider an example to illustrate how the Weight Volume Percent Calculator works:
Suppose we have a solution containing 10 grams of solute dissolved in 200 milliliters of solvent.
Using the formula:
w/v% = (10 g) / (200 mL) * 100 = 5%
So, the weight volume percent of the solution is 5%.
