Taking into account the definition of molarity, 14.028 grams of sodium chloride must be added to make 400 mL of a 0.600 M sodium chloride.

Definition of molarity

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

Moles of sodium chloride

In this case, you know:

  • Molarity= 0.600 M
  • number of moles= ?
  • volume= 400 mL= 0.400 L (being 1000 mL= 1 L)

Replacing in the definition of molarity:

[tex]0.600 M=\frac{number of moles}{0.400 L}[/tex]

Solving:

number of moles= 0.600 M× 0.400 L

number of moles= 0.24 moles

Mass of sodium chloride

Being the molar mass of sodium chloride 58.45 [tex]\frac{g}{mole}[/tex], that is the amount of mass that a substance contains in one mole, the mass of sodium chloride can be calculated as:

0.24 moles×58.45 [tex]\frac{g}{mole}[/tex]= 14.028 grams

Finally, 14.028 grams of sodium chloride must be added to make 400 mL of a 0.600 M sodium chloride.
