Question

What is the concentration of a solution with a volume of .45 L that contains .9 moles of Iron (II) chloride?

Answer 1

Answer:

the concentration of the solution is 2 mol/L.

Explanation:

Molarity is defined as the concentration of a solution expressed in terms number of moles of solute per liter of solution.

Mathematically Molarity is expressed as follow;

$Molarity = \frac{Moles \ of \ solute}{Liters \ of \ solution}$

Given;

Volume of the solution, V = 0.45 L

Moles of the solute, n = 0.9 moles

The concentration of the solution $= \frac{0.9}{0.45} = 2 \ mol/L$

Therefore, the concentration of the solution is 2 mol/L.
