Asked by CMM

If the actual density is 1.2686 g/mL and the determined density by experiment was 1.0275 g/mL, is it reasonable to conclude the obtained product was fairly pure. I am writing a lab report and these were my results and interpretation, but I am not sure if the difference between the densities (0.2411 g/mL) is too big to consider my product fairly pure?

That is a major error. It is not fairly pure.

Agreed. You do not say what the substance is or how it was made, but as the density of you material is less than that expected then contamination with water or a solvent seems likely.
