Concentrated hydrochloric acid HCl (M = 36.5 g/moL) is available as a solution with the weight fraction w of 36.0 % (density r = 1.179 g/mL at 20 °C).

Calculate the molar concentration of HCl in this solution.

Commercially available concentrated hydrochloric acid is 37.0% w/w Hcl.its density is 1.18g/ml.using this information calculate the molarity of concentrated Hcl and the mass and volume (in ml) of solution containing 0.315 moles of Hcl.

commercially available concentrated hydrochloricacid is 37.0% w/w HCL. its density is 1.18g/mL. using this information calculate (a) the molarity of concentrated HCL. (B) the mass and volume (in mL) of the solution containing 0.315 moles of HCL.

A solution is prepared by adding 50.0 mL concentrated hydrochloric acid and 20.0 mL concentrated nitric acid to 300 mL water. More water is added until the final volume is 1.00 L. Calculate [H⁺], [OH^-], and the pH for this solution. [Hint: Concentrated HCl is 38% HCl (by mass) and has a density of 1.19 g/mL; concentrated HNO₃ is 70.% HNO₃ (by mass) and has a density of 1.42 g/mL.]
