Question:

Explain what is the formula to calculate how many milliliters of 5.5 M NaOH are required to prepare 400 mL of 1.5M NaOH?

Molarity & Dilution:

The most common way of expressing the concentration of a solute in a solution in chemistry is defined as molarity:

  • Molarity is a ratio of moles of solute and the volume of a solution, such that {eq}M = \dfrac{n}{V} {/eq}.
  • Diluting a solution from an initial molarity {eq}M_1 {/eq} and an initial volume {eq}V_1 {/eq} to a final volume {eq}V_2 {/eq} allows us to identify the final molarity {eq}M_2 {/eq} from the dilution formula {eq}M_1V_1 = M_2V_2 {/eq}.

Given the initial molarity:

{eq}M_1 = 5.5~M\\ {/eq}

The molarity and the volume of the diluted solution respectively:

{eq}M_2 = 1.5~M\\ V_2 =...
