Question

4. Debbie has 2.45L of a 15.4 mol/L solution of brine (salt water). She needs to have a

0.034 mol/L solution. Debbie needs to use 50.0L of this 0.034 mol/L solution of brine
for an experiment. If she dilutes her original solution, will she have enough brine of the
correct concentration to complete her experiment or will she have to make more?

Answer 1

Debbie will not have enough brine of the correct concentration and will need to make more.

Step-by-step explanation:

To determine if Debbie has enough brine of the correct concentration to complete her experiment, we can use the dilution formula:

C1V1 = C2V2

Where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

In this case, C1 = 15.4 mol/L, V1 = 2.45L, C2 = 0.034 mol/L, and V2 = 50.0L.

Substituting these values into the formula, we can solve for C1:

15.4 mol/L x 2.45 L = 0.034 mol/L x 50.0 L

Simplifying the equation gives:

37.73 = 1.7

Since the equation is not balanced, Debbie will not have enough brine of the correct concentration.

She will need to make more brine.
