Question

How many liters of a 0.0550LiBr solution contain 0.163 moles of LiBr?

Answer 1

We can find the volume of the solution using the formula of molarity:

`\text{Molarity}=\frac{moles}{volume\text{ (L)}}\text{.}`

We have already the molarity (0.0550 M (mol/L) ) and the number of moles (0.163 moles). Clearing the formula for liters and replacing the data that we have, we're going to obtain:

`\begin{gathered} \text{Volume}=(moles)/(Molarity), \\ \text{Volume}=\frac{0.163\text{ moles}}{0.0550\text{ }(mol)/(L)}, \\ \text{Volume}=2.96\text{ L.} \end{gathered}`

The answer is that we have 2.96 liters in a 0.0550 M of LiBr solution with 0.163 moles.
