This problem is providing us with both the concentration and moles of a solute and asks for the volume in liters. At the end, the answer turns out to be 0.5 L according to the following.
MolarityIn chemistry, units of concentration are used to represent the relative amounts of both solute and solvent in different units. In this case, we refer to molarity due to the relationship between the moles of solute and the volume of solution as follows:
Thus, having both the concentration and moles, 10 M and 5 moles respectively, one can obtain the following volume after solving for it:
