Why must the following analysis be conducted in bodies of water? c. Total hardness

Please don't provide handwritten solution

The molecular weight of acetylcholine chloride is 181.7. A stock solution of 1.817 g acetylcholine is 10.0mL was prepared by the stockroom. What is the concentration of this stock solution in % w/v and in molarity? From this stock solution of acetylcholine chloride, 0.40 mL was added to the sample tube brining the total volume in the sample tube to 3.0 mL. What is the concentration of the acetylcholine chloride in the sample tube in g/mL and in molarity?

What acylium ion is formed from attached acid chloride ?

25 mL of HCl was used. I need help with all 3 trials. Thank you!

All solute dissolve in solvent? True or false

A solution of HCI is standardized against a sample which has been previously found to contain 71.22% Na2CO3, and no other basic material. The sample weighing 0.5962 g is treated with 32.7 mL of the acid and the excess acid then requires 1.52 mL of NaOH solution. If 1.00 mL of the acid is equivalent to 0.9690 mL of the NaOH, calculate for the normality of each solution.
