The new volume of the dilute solution is 0.33 L.
<u>Explanation:</u>
Using the law of Volumetric analysis, we can find the volume of the dilute solution from the stock solution or the concentrated solution of Calcium Chloride.
V1M1 = V2M2
V1 be the volume of the stock solution = 0.25 L
M1 being the molarity of the stock solution = 0.98 M
V2 be the volume of the dilute solution = ?
M2 being the molarity of the dilute solution = 0.74 M
We have to rearrange the above equation to find V2 as,
V2 = 
Now plugin the values as,
V2 = 
= 0.33 L
So the new volume of the dilute solution is 0.33 L.

Explanation:
This problem deals with balancing of chemical equations.
Every chemical equations obey the law of conservation of matter which states that "in chemical reactions, matter is usually conserved and are not produced, they are simply recombined".
Equation of reaction:
BaO₂ + H₂SO₄ ⇒ H₂O₂ + BaSO₄
Let us use a mathematical approach to balance this equation by setting up simple algebraic equations:
aBaO₂ + bH₂SO₄ ⇒ cH₂O₂ + dBaSO₄
a, b, c and d are the number of moles that will balance the equation;
Conserving Ba: a = d
O: 2a + 4b = 2c + 4d
H: 2b = 2c
S: b = d
now let a = 1
d = 1
b = 1
c = 1
we see that the equation is already balanced

It has to be intensive, which means it does not depend on the amount of the substance. Boiling point, melting point, and density are three intensive physical properties.
