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.

A railroad tank car derails and spills 36 tons of concentrated sulfuric acid. The acid is 98.0 mass% H₂SO₄ and has a density of 1.836 g/mL. (a) What is the molarity of the acid?

Determine the molarity of a solution formed by dissolving 97.7 g LiBr in enough water to yield 750.0 mL of solution.

What is the molarity of a solution that contains 17 g of NH₃ in 0.50 L of solution?

Find the molarity of a 40.0% by mass aqueous solution of sulfuric acid, H₂SO₄, for which the density is 1.3057 g/ml.

A throat spray is 1.40% by mass phenol, C₆H₅OH, in water. If the solution has a density of 0.9956 g/mL, calculate the molarity of the solution.
