Question

When 0.50 liter of a 12m solution is diluted to 1.0 liters, the molarity of the new solution is ____

Answer 1

Answer:

Final molarity  = 6 M

Explanation:

Given data:

Initial volume = 0.50 L

Initial molarity = 12 M

Final volume = 1 L

Final molarity = ?

Solution:

Formula:

M₁V₁ = M₂V₂

M₁ = Initial molarity

V₁ = Initial volume

M₂ = Final molarity

V₂ = Final volume

Now we will put the values.

12 M × 0.50 L = M₂ ×  1 L

6 M.L = M₂ ×  1 L

M₂ = 6 M.L / 1L

M₂ = 6 M
