To calculate the solubility of a compound in grams of solute per 100 grams of the solution, follow these steps:
- Determine the mass of the solute: Measure the mass of the solute that dissolves in a given amount of solvent. This is usually done by weighing the solute before and after it dissolves.
- Determine the mass of the solution: Measure the total mass of the solution, which includes both the solute and the solvent.
- Calculate the solubility: Use the formula below to calculate the solubility in grams of solute per 100 grams of the solution.
The formula to calculate solubility is:
Solubility (g/100g) = (Mass of Solute / Mass of Solution) × 100
Example:
Suppose you dissolve 20 grams of salt in 80 grams of water. The total mass of the solution is 100 grams (20g + 80g).
Using the formula:
Solubility (g/100g) = (20g / 100g) × 100 = 20g/100g
This means the solubility of salt in this solution is 20 grams per 100 grams of the solution.
By following these steps, you can easily calculate the solubility of any compound in grams of solute per 100 grams of the solution.
