Answer:

The concentration for 25 mL is 0.81 M

Explanation:

Given data:

Initial volume = 135 mL

Initial molarity = 0.150 M

New volume added = 25 mL

Concentration for 25 mL = ?

Solution:

M₁V₁    =    M₂V₂

0.150 M × 135 mL = M₂ × 25 mL

M₂ = 0.150 M × 135 mL / 25 mL

M₂ = 20.25 M.mL/25 mL

M₂ = 0.81 M

The concentration for 25 mL is 0.81 M.
