According to Le Châtelier's principle, what happens if heat is added to a system? apex

Explanation:
Le Chatelier's principle states that for a long period of time if a system is at equilibrium and it is subjected to change in concentration, temperature, volume or pressure then the system shifts to a new equilibrium.
This change will partly counter acts the applied change.
Therefore, when heat is added to the system then equilibrium will shift to the side where temperature or heat is reduced again.
For example,
Since heat is added to the system, hence, system will shift to the left side or we can say equilibrium will shift to the backward direction.

Answer : The molality, mass/mass percent, and mass/volume percent are, 0.0381 mole/Kg, 25.67 % and 32.086 % respectively.
Solution : Given,
Density of solution = 1.25 g/ml
Molar mass of (solute) = 95.21 g/mole
3.37 M magnesium chloride means that 3.37 gram of magnesium chloride is present in 1 liter of solution.
The volume of solution = 1 L = 1000 ml
Mass of (solute) = 3.37 g
First we have to calculate the mass of solute.
Now we have to calculate the mass of solution.
Mass of solvent = Mass of solution - Mass of solute = 1250 - 320.86 = 929.14 g
Now we have to calculate the molality of the solution.
The molality of the solution is, 0.0381 mole/Kg.
Now we have to calculate the mass/mass percent.
The mass/mass percent is, 25.67 %
Now we have to calculate the mass/volume percent.
The mass/volume percent is, 32.086 %
Therefore, the molality, mass/mass percent, and mass/volume percent are, 0.0381 mole/Kg, 25.67 % and 32.086 % respectively.
