Answer:
To calculate the solubility of the solution, we need to determine how many grams of salt are dissolved in 100 grams of the solution.
Given:
Mass of salt (solute) dissolved:
5 grams
Total mass of the solution:
100 grams
The solubility is usually expressed as the amount of solute (salt) per 100 grams of solvent (usually water).
First, calculate the mass of the solvent (water) in the solution:
Mass of solvent
=
Total mass of solution - Mass of solute
Mass of solvent=Total mass of solution−Mass of solute
Mass of solvent
=100 grams
−5 grams
Mass of solvent=100 grams−5 grams
Mass of solvent
=
95
grams
Mass of solvent=95 grams
Now, we want to find the solubility in terms of grams of solute per 100 grams of solvent. To do this, we use the ratio of the mass of the solute to the mass of the solvent and then scale it to 100 grams of solvent.
Solubility=(
Mass of solvent
Mass of solute)*100

So
grams of salt per 100 grams of water
Solubility≈5.26 grams of salt per 100 grams of water
So, the solubility of the salt in the solution is approximately
5.26
5.26 grams of salt per 100 grams of water at room temperature and pressure.
