I need serious help with solving this problem.
A 12.2 M solution has a volume of 4.0 L. The volume is doubled by adding water. What is the final molarity of the solution?

Lanuel

The final molarity of this diluted solution is equal to 6.0 M.

Given the following data:

  • Initial volume = 4.0 mL
  • Initial molarity = 12.2 M
  • Final volume = 8.0 mL

To calculate the final molarity of this diluted solution:

The formula for the molarity of a solution.

Mathematically, the relationship between the molarity of a solution and volume is given by the formula:

[tex]MV = k\\\\M_1V_1 = M_2V_2[/tex]

Where:

  • M is the molarity of a solution.
  • V is the volume of a solution.

Making [tex]M_2[/tex] the subject of formula, we have:

[tex]M_2 = \frac{M_1V_1}{V_2}[/tex]

Substituting the given parameters into the formula, we have;

[tex]M_2 = \frac{12 \times 4.0}{8.0} \\\\M_2 = \frac{48}{8.0}[/tex]

Final molarity = 6.0 M
