Question

A beaker contains 0.125 L of a 3.00 M solution. If the volume goes up to 0.325 L, what is the new molarity?

Answer 1

1.15 M

Step-by-step explanation:

Step 1: Given data

• Initial volume (V₁): 0.125 L

• Initial concentration (C₁): 3.00 M

• Final volume (V₂): 0.325 L

• Final concentration (C₂): ?

Step 2: Calculate the final concentration of the solution

We want to prepare a dilute solution from a concentrated one by adding water. We can calculate the concentration of the dilute solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁/V₂

C₂ = 3.00 M × 0.125 L/0.325 L = 1.15 M
