0.05 moles of HCL are added to 2 L of H2O. What is the molarity of the solution?
EleoNora [17]

The molarity of the solution made by dissolving 0.05 mole of HCl in 2 L of H₂O is 0.025 M

<h3>What is molarity? </h3>

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

Molarity = mole / Volume

<h3>How to determine the molarity </h3>
  • 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
