Answer 1

M₂ = 0.08 M

Step-by-step explanation:

Given data:

Initial volume = 25.0 mL

Initial molarity = 0.500 M

Final volume = 150.0 mL

Final molarity = ?

Solution:

Formula:

M₁V₁ = M₂V₂

0.500 M × 25.0 mL = M₂ × 150.0 mL

M₂ = 0.500 M × 25.0 mL / 150.0 mL

M₂ = 12.5 M.mL /150.0 mL

M₂ = 0.08 M
