Describe how you could make 80 mL of a 0.1 M NaCl solution.

Question:

Describe how you could make 80 mL of a 0.1 M NaCl solution.

Molarity of a Solution:

The molarity of a solution formula is indicated below, considering the solution's volume and moles of solute.

{eq}M = \dfrac{{n\left( {{\rm{mol}}} \right)}}{{V\left( {\rm{L}} \right)}} {/eq}

Where,

  • The number of moles of solute is n
  • The volume (in liters) of the solution is V

The moles of a solute or any chemical compound are evaluated as follows.

{eq}n = \dfrac{{m\left( {{\rm{Mass}}} \right)}}{{{M_{{\rm{mm}}}}\left( {{\rm{Molar}}\;{\rm{Mass}}} \right)}} {/eq}
