How many liters of a 3 M NaOH stock solution would you need to make 552 mL of a 105 mM NaOH dilution

Ganezh [65]

Answer:

0.01932 L

Explanation:

First we <u>convert 105 mM to M</u>:

105 mM / 1000 = 0.105 M

Next we <u>convert 552 mL to L</u>:

552 mL / 1000 = 0.552 L

Then we use the following equation:

C₁V₁=C₂V₂

Where:

C₁ = 3 M

V₁ = ?

C₂ = 0.105 M

V₂ = 0.552 L

We<u> input the given data</u>:

3 M * V₁ = 0.105 M * 0.552 L

And <u>solve for V₁</u>:

V₁ = 0.01932 L
