Answer:

257 mL

Explanation:

Step 1: Given data

  • Concentration of the muriatic acid solution used (C): 3.50 M (3.50 mol/L)
  • Mass of HCl (m): 32.8 g

Step 2: Calculate the moles (n) corresponding to 32.8 g of HCl

The molar mass of HCl is 36.46 g/mol.

32.8 g × 1 mol/36.46 g = 0.900 mol

Step 3: Calculate the volume (V) of solution required

We will use the following expression.

C = n/V

V = n/C

V = 0.900 mol/(3.50 mol/L)

V = 0.257 L = 257 mL
