Molarity of liquid HCl, if density is 1.17 g/cc. :

Options:

Answer:

Solution:

Explain the question : Find the molarity of liquid HCl.

Concept : This question is based on molarity from density.

Solution :

Mass = density × volume $= 1.17 g / mL \times 1000 mL = 1170 g$ .

Moles = mass $/$ molar mass $= 1170 g /36.5 g / mol \approx 32.05$ moles. Since this is the number of moles present in 1 litre, the molarity of the liquid HCl is 32.05 M .

Final answer : C
