What is the molarity of a solution which has a volume of 3 litres and contains 5.1 moles of Br2?

Respuesta :

Answer:

The molarity of the solution is 1.7 [tex]\frac{moles}{liter}[/tex].

Explanation:

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

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

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

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

In this case, you know:

  • moles of solute= 5.1
  • volume= 3 L

Replacing:

[tex]Molarity=\frac{5.1 moles}{3 L}[/tex]

Solving:

Molarity= 1.7 [tex]\frac{moles}{liter}[/tex]

The molarity of the solution is 1.7 [tex]\frac{moles}{liter}[/tex].
