Question

Calculate the volume of 4.00 molar NaOH solution required to prepare 100 mL of a 0.500 molar solution of NaOH.

Answer 1

Answer:

The answer to your question is V₁ = 12.5 ml

Explanation:

Data

Volume = V₁?

[NaOH] = C₁ = 4.0 M

Volume 2 = V₂ = 100 ml

[NaOH] = C₂ = 0.5 M

Formula of dilution

                             V₁C₁   =  V₂C₂

Solve for V₁ (original solution)

                                 V₁ = $\frac{V2C2}{C1}$

Substitution

                                V₁ = $\frac{(0.5)(100)}{4}$

Simplification

                                V₁ = $\frac{50}{4}$

Result

                                V₁ = 12.5 ml
