<h3><u>Answer;</u></h3>

Oxygen

<h3><u>Explanation;</u></h3>

<em><u>A bunsen burner attains a blue gas flame when there is enough oxygen for complete combustion. </u></em>
When there is sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
In other words; increasing oxygen supply, less black body-radiating soot is produced as a result of a more complete combustion and the reaction creates enough energy to excite and ionize gas molecules in the flame, and a blue flame is formed.

So, 57 grams of lactulose syrup needed $\frac{57g}{10g}\times 15mL=85.5mL$ volume of solution

Thus, the volume given to the patient should be, 85.5 mL
