When doing a research paper if you have paragraph coming from all the same information can put one citation at end of or every sentence?

You should not put a citation at the end of every sentence if all the sentences come from the same source. That's redundant and poor citation practice.

Instead, place a single citation at the end of the paragraph (or at the end of the last sentence if the paragraph is a single idea from one source). The citation should encompass all the information presented within that paragraph. This assumes that the information is presented as a coherent unit and is not a collection of distinct facts each needing its own source.
