what is the volume of one mole of solid iron at 25 C?

i understand that volume = m/d but how would i go about solving this?

**bobpursley**, Thursday, January 24, 2008 at 7:23amIsn't one mole of iron equal to its atomic mass in grams? Can you look up the atomic mass of iron?

**Matt**, Thursday, January 24, 2008 at 9:07amthanks, 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.
