Answer:

5 × 10⁻³ mol

Explanation:

Step 1: Given data

  • Volume of HCl solution (V): 25 cm³
  • Molar concetration of the HCl solution (C): 0.2 mol/dm³

Step 2: Convert "V" to dm³

We will use the conversion factor 1 dm³ = 1000 cm³.

25 cm³ × 1 dm³/1000 cm³ = 0.025 dm³

Step 3: Calculate the moles of HCl (n)

We will use the definition of molarity.

C = n/V

n = C × V

n = 0.2 mol/dm³ × 0.025 dm³ = 5 × 10⁻³ mol
