Commercial grade hcl solutions are typically 39.0% (by mass) hcl in water. determine the molarity of the hcl, if the solution has a density of 1.20 g/ml.

12.82 mol/L the molarity of the HCl.

Explanation:

Suppose in 100 grams of 39.0% (by mass) HCl in water.

Volume of solution = V

Density of the solution = d = 1.20 g/mL

Mass = Density × Volume

Mass of HCl = 39.0% of 100 grams=

Moles of HCl =

The molarity of the HCl = M

12.82 mol/L the molarity of the HCl.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

the answer is 75.0%.
