Question

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

Answer 1

0.01932 L

Step-by-step explanation:

First we convert 105 mM to M:

• 105 mM / 1000 = 0.105 M

Next we convert 552 mL to L:

• 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 input the given data:

• 3 M * V₁ = 0.105 M * 0.552 L

And solve for V₁:

• V₁ = 0.01932 L
