To find the in the solubility experiment, subtract the initial mass from the final mass

Sure, here are the steps to find the solubility in an experiment:

1. Measure the initial mass of the solute (the substance to be dissolved) before the experiment. This can be done using a balance or scale. Record this value.

2. Dissolve the solute in a solvent (the substance that does the dissolving) until no more solute can be dissolved. This is the point of saturation.

3. After the solute is completely dissolved, measure the final mass of the solution (solute + solvent). Again, use a balance or scale to do this and record the value.

4. Subtract the initial mass (step 1) from the final mass (step 3). This will give you the mass of the solute that was able to dissolve in the solvent.

5. The result is the solubility of the solute in that particular solvent under the conditions of the experiment. The solubility is usually expressed in terms of mass of solute per volume or mass of solvent.

Remember, solubility can be affected by factors such as temperature and pressure, so these should be kept constant during the experiment to get accurate results.
