Answer:
The number of moles of NaCl contained in 0.5000 L of a 1.5 M (Molarity) solution is 0.75 moles.
Explanation:
Molar concentration is a measure of the concentration of a solute in a solution, be it some molecular, ionic, or atomic species.
Molarity M is the number of moles of solute that are dissolved in a given volume.
The Molarity of a solution is determined by the following expression:
[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case:
Reemplacing:
[tex]1.5 M=\frac{number of moles of solute}{0.5 L}[/tex]
Solving:
number of moles of solute= 1.5 M* 0.5 L
number of moles of solute= 0.75
The number of moles of NaCl contained in 0.5000 L of a 1.5 M (Molarity) solution is 0.75 moles.
