Which would have a higher entropy?

An aqueous solution of glucose or an aqueous solution of carbon dioxide at 25 Celsius and why?

Are the concentrations the same?

Entropy is a measure of disorder. So what do you think has more disorder - an aqueous solution or a gas?

Tempted to say glucose because it is a bigger and bulkier molecule.
HOWEVER
An aqueous solution of CO2 will form carbonic acid, and as a result form a lot more molecules if the starting solutions were at the same concentrations.

This is higher in priority than the size of the molecules, so I'd say that the solution of carbon dioxide has higher entropy.

Hm good point. Would the temperature of 25 degrees affect it and give a higher entropy due to more kinetic energy etc

No i guess, that's there because at room temp. (25deg) the co2 is very soluble. If you increase the temperature though, the solubility decreases, and at a point CO2 won't dissolve anymore. near this point the kinetic energy and all those would make the Glucose solution more entropic than the aqueous co2.

That's just a guess though, chemistry tests like to mention temperatures anyway.

Which has higher entropy?
A solution of sodium chloride at 50 celsius or a solution of sodium chloride at 25 celsius.

They are both in aqueous solution. Would the 25 degrees mean that a low temperature is being used so therefore small entropy increase? Im not too sure
