Homework Help: ap chem

Posted by John on Thursday, January 24, 2008 at 4:01pm.

could you please check my work?
what is the volume of one mole of solid iron at 25 degrees c?

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.
