Isn't one mole of iron equal to its atomic mass in grams? Can you look up the atomic mass of iron?
thanks, this is how i calculated it:
1 mol Fe/.141 mol/cm^3 = 7.10 cm^3
(the .141 came from converting the density in to moles)
is that correct?
then the next step in the problem is to find the volume of 1 mol of Fe atoms assuming each atom to be spherical. the atomic radius is 0.126 nm.
so i calculated:
4/3 pi (0.126 nm)^3 = .00838 nm^3
is that correct?
thank you for your help.
