Hello, Im Mack. Hope you're doing well. :)
Here is my Correct, custom answer for the lab Question, (I also took the same assignment and got a 100% score)
Explanation:
The heating of the sodium acetate solution made it change from super-saturated to un-saturated. Yet now that it cooled back to room temperature Im sure it is saturated. it wasn't able to disolve the excess sodium acetate left over at room temperature and had to be heated so now that it is back to room temperature I Think it will not disolve the sodium acetate left in the solution until it is heated again.
Hope this helped you out,
Please feel free to comment for further help, and I'll reply asap.
<u>Have a great day my friend :)</u>

= 23.81%
