    I don't think you need hypergeometric distribution. I think it's just binomial. My stats isn't very good so I couldn't do it.

    Yeah, mine isn't very good either! I'm trying to go about it differently now. I looked up the abundance of nitrogen-15, and am currently trying a probability tree

    Binomial probability is what you need! Don't give up- this one really is annoyingly tricky until you (well, at least kind of) know what you're doing.

    After you find the specific heat of fusion (L), you use the formula,
    Q=mL. Mass is already mentioned and your answer's ready!
