Answer:
15g
Explanation:
Molar mass of acetic acid = 60g/mol
Molarity = mass ÷ molar mass
mass = 0.25 × 60
= 15g
∴ 15g of acetic acid weighed into 1L volumetric flask would give 0.25M of acetic acid.
<em>Alternatively, if the solution is being prepared from a stock solution of known concentration, (say 500mL of 0.5M solution), the formular C2V1 =C2V2 can be used to find the dilution volume.</em>
