Consider this question: What is the molarity of HCL if 35.23 mL of a solution of HCL contains 0.3366 g of HCL?

Crazy boy [7]

Answer: The molarity of HCl solution is 0.262 M

Explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Given mass of HCl = 0.3366 g

Molar mass of HCl = 36.5 g/mol

Volume of the solution = 35.23 mL

Putting values in above equation, we get:

$\text{Molarity of HCl}=\frac{0.3366g\times 1000}{36.5g/mol\times 35.23mL}\\\\\text{Molarity of HCl}=0.262M$

Hence, the molarity of HCl solution is 0.262 M.

What is the concentration of acetic acid?

castortr0y [4]

Answer:

Acetic acid is a weak monoprotic acid.

In aqueous solution it has a pKa value of 4.76.

It conjugate base is acetate (CH3COO-) A 1.0m

solution ( about the concentration of domestic vinegar) has pH of 2.4, *indicating that merely

0.4% of the acetic acid molecules are dissociated.
