Question

A 20 ml solution of sugar with a concentration of

1.0M is diluted to 120 mL, what is the new
concentration?

Answer 1

M₂ = 0.16 M

Step-by-step explanation:

Given data:

Initial volume of solution = 20 mL

Initial concentration = 1.0 M

Final volume = 120 mL

Final/new concentration = ?

Solution:

Formula:

M₁V₁ = M₂V₂

by putting values,

1.0 M × 20 mL = M₂ × 120 mL

M₂ = 1.0 M × 20 mL / 120 mL

M₂ = 20 M.mL /120 mL

M₂ = 0.16 M
