Answer:
1.75 moles are contained in 500 mL of a 3.5 M NaOH solution.
Explanation:
Molar concentration is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species and indicates the number of moles of solute that are dissolved in a given volume.
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:
Replacing:
[tex]3.5 M=\frac{number of moles of solute}{0.5 L}[/tex]
Solving:
number of moles of solute= 3.5 M*0.5 L
number of moles of solute= 1.75 moles
1.75 moles are contained in 500 mL of a 3.5 M NaOH solution.
