2Litres
The formula for calculating the molarity of a substance is expressed according to the equation below:
[tex]molarity=\frac{moles}{volume}[/tex]Given the following parameters:
moles of solution = 8 moles
molarity = 4 M
Substitute the given parameters into the formula
[tex]\begin{gathered} volume=\frac{moles}{molarity} \\ volume=\frac{8moles}{4M} \\ volume=2L \end{gathered}[/tex]Therefore the volume of litres present is 2Litres
