Muriatic acid, an industrial grade of concentrated HCl, is used to clean masonry and cement. Its concentration is 11.7 M. For ro
spin [16.1K]

383 mL of 3.50 M muriatic acid solution

Explanation:

First we calculate the number of moles of HCl:

number of moles = mass / molecular weight

number of moles of HCl = 47.7 / 35.5 = 1.34 moles

Now to determine the volume of the 3.50 M muriatic acid (clorhidric acid) solution, we use the following formula:

molar concentration = number of moles / volume (L)

volume (L) = number of moles / molar concentration

volume of the muriatic acid solution = 1.34 / 3.5 = 0.383 L = 383 mL
