Mass would crystallize out : 24 g
<h3>Further explanation </h3>Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility
- 1. Temperature:
- 2. Surface area:
- 3. Solvent type:
- 4. Stirring process:
We can use solubility graph to solve this.
solubility KClO₃ at 90°C=52 g
solubilty KCl₃ at 60°C= 28 g
Mass would crystallize out = 52 - 28 =24 g
The answer for the following problem is mentioned below.
- <u><em>Therefore the final temperature of the gas is 740 K</em></u>
Explanation:
Given:
Initial pressure of the gas () = 1.8 atm
Final pressure of the gas () = 4 atm
Initial temperature of the gas () = 60°C = 60 + 273 = 333 K
To solve:
Final temperature of the gas ()
We know;
From the ideal gas equation;
we know;
P × V = n × R × T
So;
we can tell from the above equation;
<u> P ∝ T</u>
(i.e.)
<em> </em><em> = constant</em>
=
Where;
= initial pressure of a gas
= final pressure of a gas
= initial temperature of a gas
= final temperature of a gas
=
=
= 740 K
<u><em>Therefore the final temperature of the gas is 740 K</em></u>
