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

Sure, here are the steps to find the change in mass in a solubility experiment:

1. Start the experiment and record the initial mass of the solute. This is the amount of substance you are trying to dissolve.

2. Dissolve the solute in a solvent (like water) until no more can dissolve. This is when you have reached the point of maximum solubility.

3. After reaching maximum solubility, remove the solution from the solvent. This can be done through methods like evaporation or filtration.

4. Once you have your solute separated from the solvent, measure its mass again. This is your final mass.

5. Subtract the initial mass from the final mass. The result is the change in mass.

Remember, if the final mass is less than the initial mass, the solute has lost mass (likely due to dissolution). If the final mass is more than the initial mass, the solute has gained mass (likely due to impurities or measurement error).
