Calculate the average mass, in grams, of an iron atom.
To calculate the average mass of an iron atom, you need to know its atomic mass.
1. Find the atomic mass of iron (Fe) on the periodic table. The atomic mass of iron is approximately 55.845 atomic mass units (amu).
2. Convert atomic mass from amu to grams. To convert, use the conversion factor that says 1 amu is equal to 1.66054 x 10^-24 grams. Multiply the atomic mass of iron by this conversion factor:
55.845 amu x (1.66054 x 10^-24 g/1 amu) = 9.273 x 10^-23 grams
So, the average mass of an iron atom is approximately 9.273 x 10^-23 grams.
