Taking into account the definition of molarity, the molarity of solution of sodium sulfate is 0.0732 
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
<h3>Molarity of solution of sodium sulfate.</h3>
In this case, you have:
- number of moles of sodium sulfate=
(being 142 g/mole the molar mass of sodiums sulfate) - volume= 500 mL= 0.5 L (being 1000 mL= 1 L)
Replacing in the definition of molarity:
Solving:
Molarity= 0.0732
Finally, the molarity of solution of sodium sulfate is 0.0732 .

Answer:
The difference is 2 pH units.
Explanation:
Let's give an arbitrary value to the H⁺ concentration of solution A, [H⁺]ₐ:
If that's the case then the pH of solution A would be:
----
The H⁺ concentration of solution B ( [H⁺]ₓ ) is 100 higher than that, so:
- [H⁺]ₓ = 0.001 * 100 = 0.1 M
And its pH:
So the difference in pH values is:
The dry ice absorbs heat from the air in the flask and become CO2 gas directly. So the heat flow from air to dry ice. And the CO2 gas increase the amount of the air. Though the temperature decreases, the balloon still inflates.
