PLEASE HELP FAST!!! What is the molarity of a solution that contains 42.9 mol of calcium chloride (CaCl2) in a 45.0L solution?

Respuesta :

Answer:

The molarity of the solution is 0.95 [tex]\frac{moles}{liter}[/tex].

Explanation:

The molarity of a solution is a measure of concentration that indicates the number of moles of solute that are dissolved in a given volume. It 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= 42.9 moles
  • volume= 45 L

Replacing in the definition of molarity:

[tex]Molarity=\frac{42.9 moles}{45 L}[/tex]

Solving:

Molarity= 0.95 [tex]\frac{moles}{liter}[/tex]

The molarity of the solution is 0.95 [tex]\frac{moles}{liter}[/tex].
