 Curious | Calculating Atomic Mass Hello. I have this paper that gives me the following information and asks me to find the atomic mass for each isotope of iron. Red Iron-----56.782 grams--for--44.37% of the total sample Yellow Iron--54.765 grams--for--38.65% of the total sample Black Iron---53.108 grams--for--16.98% of the total sample If anyone has any insight into what I'm supposed to do in order to solve this, please post. Thanks in advance. | |

 Explaining | Re: Calculating Atomic Mass well, this problem looks kinda weird... can you clarify a bit? well, for what i know, red iron, you mean some type of iron ore? well, thats gotta be Fe2O3. black iron, hmm, probably Fe3O4, which is magnetic stone... yellow iron, i have no idea... maybe some sulfide..hmm, FeS2 ?  the probelm still doesnt make sense to me, how do you calculate... atomic mass of isotope given such.... information.  ---------------- I have mistaken, apologized, and taken the consequences. My only regret, was for how I was bothered by the unchangable. | |

| Explaining | Re: Calculating Atomic Mass wait, are you sure that you are suppose to find the atomic mass of iron isotopes? it makes more sense to calculate the mass of "iron element" in the whole sample. ---------------- I have mistaken, apologized, and taken the consequences. My only regret, was for how I was bothered by the unchangable. | |

| Curious | Re: Calculating Atomic Mass The names (Red, Yellow, Black Iron) are irrelevant as far as I can tell. They're just there for the sake of having names, that's all. I'm almost positive you're supposed to find the mass of each, but I could be wrong. I'm almost as confused as you are, so let's just forget about it. The assignment is due tomorrow but I'll just have to ask about it once I get to class. Thanks anyway. | |

 Creating | Re: Calculating Atomic Mass It is a horribly phrased question. Take the weighted average.
