1. The problem statement, all variables and given/known data For my IB extended essay I want to determine the quantity of salt in comercial popcorns, and analyze if this amount of salt consumption is bad for one's health. I've made my investigation, and read that the levels of salt in these popcorns are quite high, and in the long run can cause many health problems such as high blood pressure and hearth disease. I want your help in choosing the best method to prove this, please, any idea can help. 2. Relevant equations I don't know any relevant equations for this, but I do know that sodium chloride's chemical formula is NaCl, but this is just common knowledge. 3.
