What volume of concentrated HCl solution contains 125 g of HCl?

Short Answer

Expert verified

282 mL of concentrated HCl solution contains 125 g of HCl

Step by step solution

01

Determine concentration of HCl

Mass of HCl = 125 g

Molecular weight of HCl = 1 + 35 = 36 g/mol

Moles of HCl = 125 g/ 36 g/mol = 3.472 mol

Concentration of HCl = 12.19 mol/liter

02

Determine the volume of HCl

Molarity = Moles of HCl / liters of solution

=3.472 mol / 12.19 mol/liter

= 0.282 L

= 282 mL
