Determine the molarity of an aqueous solution that is 37.2% in HCl. The density of this solution

Question:

Determine the molarity of an aqueous solution that is 37.2% in HCl. The density of this solution is 1.034 g/mL.

Strategy

Write the concentrations as fractions.Given concentration % mass HC1 = 37.2 g HC1 100 g solution Desired units Molarity of HC1 = mol HCl L solution

The units in the numerator of percentage composition can be easily converted to moles, and we can use the density of the solution to convert from grams of solution to volume of solution.
