Enough solvent to make 1.00 L of solution.

Further explanation

The Problem

To make a 0.500 M solution, one could take 0.500 moles of solute and add?

The Process

  • A solution consists of a solute and a solvent.
  • There are several ways to express the concentration of a solution, one of which is molarity. Molarity is also known as molar concentration with the symbol unit M or molar or mol/L.
  • The molarity (M) of a solution is calculated by taking the moles of solute and divided by the number of liters of solution.

[tex]\boxed{ \ molarity = \frac{moles \ of \ solute}{liters \ of \ solution} \ }[/tex]

Therefore, to make a 0.500 M solution, we could take 0.500 moles of solute and add enough solvent to make 1.00 L of solution.

[tex]\boxed{ \ \frac{0.500 \ moles}{1.00 \ L \ of \ solution} = 0.500 \ M \ }[/tex]

Notes

  • The concentration of the solution can also be expressed in molality.
  • The symbol unit of molality is m or molal or mol/kg.
  • The molality of a solution is calculated by taking the moles of solute and dividing by the kilograms of solvent.

[tex]\boxed{ \ molality = \frac{moles \ of \ solute}{kilograms \ of \ solvent} \ }[/tex]

As an example, to make a 0.500 m solution we could take 0.500 moles of solute and add 1.00 kg of solvent.

In order to make a 0.500 M solution, one could take 0.500 moles of solute and add 1.00 L of solvent.

The molarity (M) is defined as the number of moles of solutes per liter of solvent. In other words:

            molarity of a solution = mole of solute/liter of solvent

Hence, in order to make 0.500 M solution, 0.5 moles of solute would have to be dissolved in a 1-liter volume of solvent.

number of moles = 0.500, volume = 1 L

Molarity = 0.500/1.00

               = 0.5 M or mole/dm3
