Question

What is the concentration of a dextrose solution prepared by diluting 16 mL of a 1.0 M dextrose solution to 25 mL using a 25 mL volumetric flask?

Answer 1

Answer:

0.64 M

Explanation:

Step 1: Given data

• Initial concentration (C₁): 1.0 M

• Initial volume (V₁): 16 mL

• Final concentration (C₂): ?

• Final volume (V₂): 25 mL

Step 2: Calculate the final concentration of the dextrose solution

We want to prepare a diluted solution from a concentrated one. We can find the final concentration using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 1.0 M × 16 mL / 25 mL

C₂ = 0.64 M
