Directions: Draw into a clean dry 125-mL Erlenmeyer flask about 75 mL of standardized HCl solution (about 0.1 M) from the stock solution on the reagent shelf. This amount should provide all the standard acid you will need; do not waste it. Record the molarity of the HCl.

How do you calculate the molarity of 75 mL of HCl?

The reagent label should list it and be about  0.1 M

Interesting...my lab partner recorded 0.1030 M, but I can't figure out how she got that number. Further in the calculation section, it asks for Molarity of the standardized HCl as well. If it was simply 0.1 M I don't think they would ask to calculate this.

Does the molarity change based on how much HCl you put into your flask? Because I know molarity is MOL per Liter. But in my case it's 75 mL.

What did the label on the reagent bottle indicate?
I don't see where they ask you to calculate it, it looked like they merely asked you to record it.
In order to calculate it, you would need to know more about how the stock reagent was prepared.

Was there any source of HCl in your flask other than the stock reagent?
The total amount of HCl in the solution should be proportional to the molar concentration of the solution and to the volume of the solution.

After talking with the lab partner, it was labeled on the bottle. :)
