Iron has unit cell edge length of 286.65pm. If density of iron is 7.87g/cm3. Calculate nature of unit cell

Answer: calculate the equilibrium concentration of reactants and products.If the radius of the copper atom is 127.8 pm, the density of the copper metal is calculated.A = 286.65 PM = 286.65 x 10-10 cm density ( σ ) =.The mass of 7.874 g cm-3 Fe =.56.0 u Z = 2. description: plz
