Calculating Atomic Mass


Aguraki

Recommended Posts

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.

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. :)

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.
