Answer 1

The molarity of the solution made by dissolving 0.05 mole of hydrogen chloride (HCl) in 2 L of water (H₂O) is 0.025 M

What is molarity?

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

How to determine the molarity

• Mole of HCl = 0.05 mole
• Volume = 2 L
• Molarity =?

Molarity = mole / Volume

Molarity = 0.05 / 2

Molarity = 0.025 M

Thus, the molarity of the solution is 0.025 M
