I'm a chemistry major and I've done a few poster presentations and an oral presentation. I have to put together an academic resume for a class. I was told to include mt presentations.

So yes, assuming your poster presentations are academic/research related, it's appropriate to put them in your CV, though in-class presentations are typically not included.
General comments: a CV is different than a resume so there's a lot of flexibility in what you include and how you format it. Still, there are some dos and don'ts.

Then for each presentation, list the title, venue including conference name and date. E.g.
