Question

what is the molarity of a solution that contains 2.62 mol HCL in 2.50 L of solution

Answer 1

Answer:

1.048 moles/L

Explanation:

• Molarity or concentration is the number of moles present in one liter of a solution. It is given by moles per liter or moles per dm³.
• The relationship between molarity , moles and volume of a solution is given by;

Molarity = Moles ÷ Volume

In this case;

Moles of HCl = 2.62 moles

Volume of HCl = 2.5 L

Therefore;

Molarity = 2.62 moles ÷ 2.5 L

             = 1.048 moles/L or

             = 1.048 M

Therefore, the molarity of HCl is 1.048 moles/L
