Question

Calculate the mass of HCl that is contained in 54.0 mL of an aqueous HCl solution that has a density of 1.19 g cm^–3 and contains 37.21% HCl by mass. Use the correct number of significant figures in your answer.

Answer 1

Step-by-step explanation:

Since density = mass/volume

Mass of solution = density x volume = (1.19)(54.0) = 64.26 g

Mass of HCI = (64.26)(0.3721) = 23.9 g
