Calculate the concentration of an acetic acid solution prepared by mixing 13.5mL of 10.0M acetic acid with 250.0mL of .15M NaCl solution.

I don't see how the NaCl will affect the M except by dilution.

10.0 M x (13.5/(250+13.5) = ?

To calculate the concentration of the resulting acetic acid solution, you need to consider the amount of acetic acid and the total volume of the solution.

Step 1: Calculate the moles of acetic acid
First, determine the moles of acetic acid by using the formula:

moles = concentration x volume (in liters)

Given:
Concentration of acetic acid (C1) = 10.0 M
Volume of acetic acid (V1) = 13.5 mL = 13.5/1000 L = 0.0135 L

moles of acetic acid = 10.0 M x 0.0135 L

Step 2: Calculate the moles of NaCl
Next, calculate the moles of NaCl in the solution by using the same formula:

moles = concentration x volume (in liters)

Given:
Concentration of NaCl (C2) = 0.15 M
Volume of NaCl solution (V2) = 250.0 mL = 250/1000 L = 0.25 L

moles of NaCl = 0.15 M x 0.25 L

Step 3: Calculate the total moles of acetic acid in the resulting solution
Since acetic acid does not react with NaCl, the moles of acetic acid will remain unchanged. Therefore, the total moles of acetic acid in the resulting solution will be the sum of moles from Step 1 and moles from Step 2.

Total moles of acetic acid = moles of acetic acid (Step 1) + moles of NaCl (Step 2)

Step 4: Calculate the total volume of the resulting solution
To find the total volume of the resulting solution, you need to add the volumes of acetic acid and NaCl solution together.

Total volume of resulting solution = volume of acetic acid (V1) + volume of NaCl solution (V2)

Step 5: Calculate the concentration of the resulting acetic acid solution
The concentration of the resulting acetic acid solution is the moles of acetic acid (Step 3) divided by the total volume of the solution (Step 4).

Concentration of the resulting acetic acid solution = Total moles of acetic acid / Total volume of the resulting solution

Now, plug in the values from the given information into the formulas above and calculate the concentration.
