Question

You have 87.0mL of a 0.500M stock solution that must be diluted to 0.100M. What is the final volume g

Answer 1

435 mL

Step-by-step explanation:

Step 1: Given data

• Initial volume (V₁): 87.0 mL

• Initial concentration (C₁): 0.500 M

• Final volume (V₂): ?

• Final concentration (C₂): 0.100 M

Step 2: Calculate the final volume of the solution

We want to prepare a diluted solution from a concentrated one. We can calculate the final volume of the solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₂ = C₁ × V₁ / C₂

V₂ = 0.500 M × 87.0 mL / 0.100 M

V₂ = 435 mL
