Hey all, did a chem lab today, but i am confused about a question. I got an answer with a procedure that makes sense (to me), but everyone's answers were different. I have a picture of what I did.

So, we have 1 mL p-phenitidine and 1.6 mL of acetic anhydride.

Density of phenitidine is 1.06 g/mL and anhydride is 1.08 g/mL

Find which one is the limiting reagent, and knowing that, calculate theoretical yield.

Here is what I got, circled. I am wondering why it is different from everyone else's...
