Answer 1

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)

`Molarity=\frac{moles\text{ of solute}}{Liters\text{ of solution}}`

Is given that,

- Molarity = 0.312 M = 0.312 mol/L

- moles of solute = 0.078 mol

Now, replacing in the formula

`0.312(mol)/(L)=\frac{0.078mol}{Liters\text{ of solution}}`

Then, solving for liters of solution

`Liters\text{ of solution}=(0.078mol)/(0.312(mol)/(L))=0.25L`

Finally, since we need the volu
