Title: A 13g sample of calcium reacts with bromine to form 24g of calcium bromide. How many grams of bromine are used? Post by: lespink29 on Nov 7, 2012 My bro is out of school, so I'm tutoring him in chemistry. Can someone refresh me on how to do this? Something with percent change in mass I believe. Thanks!
