Calculate the molarity of the HCl from the volumes of acid and base and the molarity of the NaOH. Use the following equation:

(molarity of acid)x(volume of acid)=(molarity of base)x(volume of added base)

0.600000001 M of HCl * 0.025L=
0.223713647 M of NaOH * 0.06705L

To calculate the molarity of the HCl, we can use the equation:

M1V1 = M2V2

where M1 is the molarity of the HCl, V1 is the volume of the HCl, M2 is the molarity of the NaOH, and V2 is the volume of the NaOH.

Given:
HCl volume = 25 mL = 0.025 L
NaOH volume = 67.05 mL = 0.06705 L
Molarity of NaOH = 0.223713647 M

Substituting the values into the equation, we have:

M1 * 0.025 L = 0.223713647 M * 0.06705 L

Solving for M1:

M1 = (0.223713647 M * 0.06705 L) / 0.025 L

M1 = 0.600000001 M

Therefore, the molarity of the HCl is approximately 0.600000001 M.

To calculate the molarity of HCl, we need to use the equation M1V1 = M2V2, where M1 is the molarity of HCl, V1 is the volume of HCl, M2 is the molarity of NaOH, and V2 is the volume of NaOH added.

Given the following values:
- Volume of HCl = 25 mL = 0.025 L
- Volume of NaOH added = 67.05 mL = 0.06705 L
- Molarity of NaOH = 0.223713647 M

First, we calculate the moles of NaOH by using the formula:
Moles = Molarity * Volume
Moles of NaOH = 0.223713647 M * 0.06705 L = 0.015000 moles

Next, we can calculate the molarity of HCl using the formula:
Molarity = Moles / Volume
Molarity of HCl = 0.015000 moles / 0.025 L = 0.600000001 M

So, the molarity of HCl is approximately 0.600000001 M.
