Question

A 33.4 mM (millimolar) solution was made using 0.252 L of a 315 mM solution. What is the final volume in L? Give your answer to 2 decimal places.

Answer 1

To calculate the final volume of the solution, we can use the equation:

C1V1 = C2V2

where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume.

Given:
Initial concentration (C1) = 315 mM
Initial volume (V1) = 0.252 L
Final concentration (C2) = 33.4 mM
Final volume (V2) =?

Plugging in the values into the equation:

(315 mM)(0.252 L) = (33.4 mM)(V2)

Solving for V2:

V2 = (315 mM)(0.252 L) / (33.4 mM)
V2 = 2.37 L

Therefore, the final volume of the solution is 2.37 L, rounded to 2 decimal places.
