Please Help!! I need help with a math/chemistry problem: What percent of the total mass of one atom of iron comes from electrons. The mass of one iron atom is 9.274 x 10^-23. The mass of one electron is 9.110x10^-28. Please show the steps. Thank You!!

This is a pretty obvious homework question. By simply doing if for masjete, you have helped him to cheat on his homework. You have deprived him of the need to think for himself. When giving help on questions like these, please leave out some information. Make the people do some of the work for themselves. Tell them how to get the answer, but don't do the work for them.

Glenn we have had this discussion before... do you think of a better way to have him work at it .. that question is easy to answer showing either a lack of understanding or as you contend an easy way out... I preffer the former.. PS masjete has only one blog out there ... hardly the person to do a homework dump.... cheat! absurb... I guess he could get the book and read .. but once at home and you read and it just doesn't click .. what next .. ask someone ... he did ... ah Initiative or cheat... notice he asked the how.. not just the answer... yeah but he may need to show the how as part of the homework... Well my purpose is not a rant here so I'll let up... and be on my way...
Have a pleasant day .. I am selective on what I answer.. try to interpret the sincerity if one can....

I doubt she had just one question on her homework...and she didn't just post seperate questions for each homework problem like many cheaters do on this site. I have no doubt that she was literally stuck on this problem, and had no resources. With something as mathematically demanding as chemistry, a step by step sample problem WITH answers is the only sure way to know that you are completing the steps correctly. Giving her the steps, but leaving her unsure of the answers is not only INCREDIBLY diffucult to do linguistically with a multistep math problems (while keeping everything coherent), it also leaves people as unsure of their abilities as they were at the beginning. Her overall grade in this chemistry course will depend on her ability to solve problems like this herself...and it will not be affected by a single homework problem on a single homwork assignment that is used as an example to teach her how to deal with future occurances of its kind.

This really really isn't that difficult of a problem. It is simply finding a percentage. Take the mass of an electron. Multiply it by the total number of electrons in an iron atom. Divide by the average mass of an iron atom. Multiply by 100 and you are done. Personally, the fact that she could not do this on here own shows how the school systems are failing our students. Someone should not be in a class where they have to deal with exponents if they don't know how to figure out a fairly simple percentage. Note, the latter is not so much a criticism of masjete as it is a criticism of the system that has failed to educate her on something so simple.
