Answer to Question #249904 in Chemistry for dam

Question

what volume of 6.0 M NaOH solution is needed to produce 3.0 L of 0.1 m solution

Answer 1

c₁ = 6.0 M

V₁ = unknown

c₂ = 0.1 M

V₂ = 3.0 L

Solution:

The equation for dilution calculations can be used

where:

c₁, V₁ - the molarity and volume of the concentrated solution

c₂, V₂ - the molarity and volume of the diluted solution

 

Thus:

(6.0 M) × V₁ = (0.1 M) × (3.0 L)

V₁ = (0.1 M × 3.0 L) / (6.0 M) = 0.05 L

V₁ = 0.05 L or 50 mL

 

Answer: 0.05 L of 6.0 M NaOH solution is needed to produce 3.0 L of 0.1 m solution.
