Question: The chemist obtained a proton NMR spectrum of a sample of the isolated Product A. If the sample were contaminated with acetone, how many extra signals corresponding to the acetone would be present in the spectrum?

Answer: 1

I just want to make sure I'm understanding this correctly. There would only be one more extra signal because the 2 methyl groups on acetone are the only "extra H's", and since they are in similar environments (ie, they are 3 hydrogens surrounding 1 carbon) this would result in only one extra signal, correct?

Yes, the 6 hydrogens are identical as far as HNMR is concerned.
