Problem

Write a detailed set of instructions for making two solutions: (1) 100 mL of 16 MNaOH from solid sodium hydroxide and (2) 1.00 L of 0.1 M NaOH from your first solution. You have in your lab: volumetric flasks marked to contain 100.0 mL and 1.000 L, a graduated cylinder, and a balance.

Calculate the volume (in mL) of 16 M NaOH solution needed to make a 1.00 L solution of 0.1 M NaOH.

Solution

We are being asked to find the volume of 16 M NaOH needed to make 1.0 L of 0.1 M NaOH

We are preparing a diluted solution from a more concentrated stock solution. When dealing with dilution we will use the following equation:

$\boxed{{\mathbf{M}}_{\mathbf{1}}{\mathbf{V}}_{\mathbf{1}}\mathbf{=}{\mathbf{M}}_{\mathbf{2}}{\mathbf{V}}_{\mathbf{2}}}$

M₁ = initial concentration
V₁ = initial volume
M₂ = final concentration
V₂ = final volume
