Answer:
[tex]\boxed{\text{2 mol/L}}[/tex]
Step-by-step explanation:
[tex]c = \dfrac{ \text{moles} }{ \text{litres}}\\\\c = \dfrac{n }{V }[/tex]
Data:
n = 5 mol
V = 2.5 L
Calculation:
[tex]c = \dfrac{ \text{5 mol} }{\text{2.5 L}} = \text{2 mol/L}[/tex]
The molar concentration of the solution is [tex]\boxed{\textbf{2 mol/L}}[/tex].
