Question

Which solution is most dilute?

Answer 1

C. 0.1 M HCl

Explanation:

The solution with the lowest molarity is the most dilute of all.

This is why the choice is 0.1M of HCl.

Molarity is the same as concentration. The unit "M" denotes mole per liter volume of solution.

• Molarity is defined as the number of moles of solute in a give volume of solution.
• 0.1M means 0.1mole of HCl is dissolved in 1liter of solvent.
• The higher the number of moles dissolved and the more the concentration of the solution will be.

The order of increasing concentration is:

  0.1M < 0.2M< 0.3M < 0.4M
