If 2.0 ml of water is added to 8.0 ml of a 0.30 m solution to make a new solution with a total volume of 10.0 ml, what is the concentration of the new solution?

To solve this we use the equation, 

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

0.30 x 8 = M2 x 10

M2 = 0.24 m of the solution


Hope this answers the question. Have a nice day.

The concentration of the new solution is 0.24 M

Data obtained from the question

  • Molarity of stock solution (M₁) = 0.3 M
  • Volume of stock solution (V₁) = 8 mL
  • Volume of water = 2 mL
  • Volume of diluted solution (V₂) = 10 mL
  • Molarity of diluted solution (M₂) =?

How to determine the molarity of diluted solution

M₁V₁ = M₂V₂

0.3 × 8 = M₂ × 10

2.4 = M₂ × 10

Divide both side by 10

M₂ = 2.4 / 10

M₂ = 0.24 M
