Understanding Solubility
* Solubility is the maximum amount of a substance (the solute) that can dissolve in a given amount of another substance (the solvent) at a specific temperature.
* A saturated solution is a solution where the solute is at its maximum concentration, meaning no more can dissolve at that temperature.
Calculating Solubility
1. Units: Solubility is usually expressed in grams of solute per 100 mL of solvent (g/100 mL).
2. Information Needed:
* Mass of Solute (g): You need to know how much of the substance (in grams) you dissolved.
* Volume of Solvent (mL): You need to know the volume of ethanol (in milliliters) used to make the solution.
3. Calculation:
* Divide the mass of the solute by the volume of the solvent.
* Multiply the result by 100 to get the solubility in g/100 mL.
Example
Let's say you dissolved 15 grams of sugar in 50 mL of water to create a saturated solution. Here's how to calculate the solubility of sugar in water:
* Solubility (g/100 mL) = (15 g / 50 mL) * 100 = 30 g/100 mL
Applying it to Your Problem
You need to provide the following information to calculate the solubility of the substance in ethanol:
* The mass of the substance (g) that was dissolved.
* The volume of ethanol (mL) used to create the saturated solution.
Once you have this information, you can follow the steps above to calculate the solubility.
