INFORMATION:

We know that:

- An intravenous solution has a concentration of glucose equal to 0.312 M

And we must find the volume of solution needed to deliver 0.078 moles of glucose to the patient

STEP BY STEP EXPLANATION:

To find it, we need to use the formula of Molarity (concentration)

[tex]Molarity=\frac{moles\text{ of solute}}{Liters\text{ of solution}}[/tex]

Is given that,

- Molarity = 0.312 M = 0.312 mol/L

- moles of solute = 0.078 mol

Now, replacing in the formula

[tex]0.312\frac{mol}{L}=\frac{0.078mol}{Liters\text{ of solution}}[/tex]

Then, solving for liters of solution

[tex]Liters\text{ of solution}=\frac{0.078mol}{0.312\frac{mol}{L}}=0.25L[/tex]

Finally, since we need the volu
