what do you need to recall it for? this isn't something to memorize. the answers right there in front of you. you have something in unites of "calories/gram" and you ahve something in units of "grams". it only takes a small degree of common sense to figure out how to get an answer in units of "calories".dochall22 said:seriously, i'm helping someone with some chem quiz study guide, and i didnt want to have to look it up, sorry if i cant recall EVERYTHING... geeze
i had just told him. i know where to get the answer, i know thse really cool guys who are REALLY HELPFUL!!!
I told him you'd have it answered in less than a minute, and what do i get? Trash talking, geeze, and you guys want to be doctors?
