Answer:
Oxygen is solvent and Helium is solute.
Explanation:
Helium is a complety inert gas which do not react with other compounds whereas, oxygen can take part in chemical reaction with many compounds.
- if we mix 15 mL of oxygen and 5mL of helium then the oxygen is the solvent and helium is solute.
- In a mixture the compound with the greater volume is solvent and the compound with lwss volume is solute.
- in this case, oxygen has greater volume than that of helium so oxygen is solute and helium is solvent here.
