Answer:
625 mL
Explanation:
From the question given above, the following data were obtained:
Volume of stock solution (V₁) = 250 mL
Molarity of stock solution (M₁) = 5 M
Molarity of diluted solution (M₂) = 2 M
Volume of diluted solution (V₂) =?
The volume of the diluted solution can be obtained by using the dilution formula as illustrated below:
M₁V₁ = M₂V₂
5 × 250 = 2 × V₂
1250 = 2 × V₂
Divide both side by 2
V₂ = 1250 / 2
V₂ = 625 mL
Therefore, the volume of the diluted solution is 625 mL.

The species that is the conjugate acid is HC₂H₃O₂(aq). The correct option is d.
<h3>What are conjugate acid?</h3>
Conjugates acids are those acids which are made when an acid donates a proton to a base according to Bronsted Lowry theory.
In other words, we can say that it is an acid with hydrogen ion. An example is water (base) reacting with an acid to form the hydronium ion (conjugate acid).
Thus, the correct option is d, HC₂H₃O₂(aq).
