Answer:
The formula to calculate the number of liters of a solution is:
(volume of solution) = (amount of solute) / (molarity)
where
(amount of solute) = 2.5 moles
(molarity) = 2.0 M
Plugging in the values:
(volume of solution) = (2.5 moles) / (2.0 M)
(volume of solution) = 1.25 L
Therefore, 1.25 liters of solution can be produced from 2.5 moles of solute if a 2.0M solution is needed.
