Question

How many liters of 3.5 M solution can be made using 23 moles of LiBr *must show work to get credit*

Answer 1

Answer: 6.57 L of solution can be made.

Step-by-step explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

`\text{Molarity of solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (L)}}` .....(1)

Given values:

Molarity of LiBr = 3.5 M

Moles of LiBr = 23 moles

Putting values in equation 1, we get:

`3.5mol/L=\frac{23mol}{\text{Volume of solution}}\\\\\text{Volume of solution}=(23mol)/(3.5mol/L)=6.57L`

Hence, 6.57 L of solution can be made.
