chemistry questions

I'm working on a chemistry question and need an explanation and answer to help me learn.

Analysis (Provide complete answers to the following questions):

• Provide the final masses for sucrose, aspirin and your unknown component

• Calculate the % recovery of Panacetin as follows:

% recovery = 𝑚𝑎𝑠𝑠 𝑜𝑓 𝑠𝑢𝑐𝑟𝑜𝑠𝑒 + 𝑚𝑎𝑠𝑠 𝑜𝑓 𝑎𝑠𝑝𝑖𝑟𝑖𝑛 + 𝑚𝑎𝑠𝑠 𝑜𝑓 𝑢𝑛𝑘𝑛𝑜𝑤𝑛
𝑜𝑟𝑖𝑔𝑖𝑛𝑎𝑙 𝑚𝑎𝑠𝑠 𝑜𝑓 𝑃𝑎𝑛𝑎𝑐𝑒𝑡𝑖𝑛 𝑠𝑎𝑚𝑝𝑙𝑒 x 100%

• Calculate the % composition for each of the components of Panacetin based on the total
mass of the components recovered.

Example:% composition of sucrose =𝑚𝑎𝑠𝑠 𝑜𝑓 𝑠𝑢𝑐𝑟𝑜𝑠𝑒
𝑡𝑜𝑡𝑎𝑙 𝑚𝑎𝑠𝑠 𝑜𝑓 𝑐𝑜𝑚𝑝𝑜𝑛𝑒𝑛𝑡𝑠 𝑟𝑒𝑐𝑜𝑣𝑒𝑟𝑒𝑑 x 100%

Perform similar % composition calculations for aspirin and the unknown also.

• Provide your melting point range for the unknown component (pick your best melting
point range determination).

• Provide the name of the unknown component based on your results.

• Exercises: Provide answers to the following Exercises:
Experiment 2 Exercises: 1, 2, 5 (Draw structures for all organic compounds in the
balanced reactions)
Experiment 3 Exercises: 1, 3a,b

• List 3 sources of error in your experiment. Please note that these should not be
hypothetical, but rather sources of error that you believe affected your own experimental
results.

I will send the photo of the noot book.
