Answer:
55g NH₄Cl / 100g Water
Explanation:
Solubility of a substance define the amount of solute per solvent in a saturated solution. The solution can dissolve additional solute if heated.
In the problem, as the first crystal appears at 61°C the solubility in this temperature is the concentration of the solution, that is:
2,75g NH₄Cl / 5,0g water ₓ 100 = <em>55g NH₄Cl / 100g Water</em>

Answer:
The answer to your question is Volume = 0.7 l
Explanation:
Data
Volume 1 = V1 = 0.746 l
Pressure 1 = P1 = 94.6 kPa
Volume 2 = V2 = ?
Pressure 2 = 101.33 kPa
Process
To solve this process use Boyle's law.
P1V1 = P2V2
-Solve for V2
V2 = P1V1/P2
-Substitution
V2 = (94.6 x 0.746) / 101.33
-Simplification
V2 = 70.57 / 101.33
-Result
V2 = 0.696 l ≈ 0.7 l
