What is the concentration of a dextrose solution prepared by diluting 15 mL of a 1.0 M dextrose solution to 25 mL using a 25 mL volumetric flask

Answer:

C₂ = 0.60 M

Explanation:

Step 1: Given data

  • Concentration of the concentrated solution (C₁): 1.0 M
  • Volume of the concentrated solution (V₁): 15 mL
  • Concentration of the diluted solution (C₂): ?
  • Volume of the diluted solution (V₂): 25 mL

Step 2: Calculate the concentration of the diluted dextrose solution

We will use the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 1.0 M × 15 mL / 25 mL

C₂ = 0.60 M
