Answer:

The molarity of the solution is 1.1 [tex]\frac{moles}{liter}[/tex]

Explanation:

Molarity is a measure of the concentration of that substance that is defined as the number of moles of solute divided by the volume of the solution.

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

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

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

In this case

  • number of moles of solute= 0.564 moles
  • volume= 0.510 L

Replacing:

[tex]molarity=\frac{0.564 moles}{0.510 L}[/tex]

Solving:

molarity= 1.1 [tex]\frac{moles}{liter}[/tex]

The molarity of the solution is 1.1 [tex]\frac{moles}{liter}[/tex]
