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.
If It takes 60mL of 0.20M of sodium hydroxide (NaOH) to neutralize 25 mL of carbonic acid (
), then the concentration of the carbonic acid is 0.24M
The reaction between NaOH solution and is written below
Volume of NaOH, 
= 60 ml
Volume of , 
Molarity of , 
Molarity of NaOH, 
Number of moles of , 
Number of moles of NaOH, 
The mathematical equation for neutralization reaction is:
Substitute 
, , , = 60ml, and into the equation above in order to solve for 
Therefore, the concentration of the carbonic acid is 0.24M
