how do i solve this problem? 3. Calculate the density of a rod of metal in g/cm', with a mass of 9.58g, a diameter of 8 mm (0.8cm) and a height of 3.5cm. Volume = Density =
Could you please explain in depth how you come to the answer on this? I understand that the atomic mass, m = 55.85 g/mole and the radius, r = 1.25 a ---- r = 1.24 x 10 ^-8 But for BCC how do you find the atomic number? I know it is Z = 2. but how do you find it and what does it signify? Also, for BCC how do you find r? I know it is ((sqrt 3)*9)...
Atomic densities and atomic volumes Problem 3. In this problem, we will calculate the atomic density ) and atomic volume () of two different pure metallic solids, Iron (Fe) and aluminum (AI). We will compare and contrast two different calculation methods flabeled Method I and Method II below. We will exploit the technique of "DIMENSIONAL ANALYSIS in our calculations. Method I. Calculate p and n based on knowledge of the mass density of the solid (the symbol for mass density...
