Explanation:
From the question we are told that
The density of lead is![\rho_l = 11.36 \ g/cm^3](/tpl/images/0748/9324/56b05.png)
The atomic weight is![M_w = 207.19 \ g/mol](/tpl/images/0748/9324/74c34.png)
The Avogadro's number is![N_a = 6.022 * 10^{23} \ \frac{atom}{mol}](/tpl/images/0748/9324/8be44.png)
Generally for FCC the number of atom is n = 4
Generally the volume of a unit FCC cell is mathematically represented
Generally the lattice parameter is mathematically represented as
=>![a_o = 4.95 *10^{-8} \ cm](/tpl/images/0748/9324/9a602.png)
Generally the radius of the lead is mathematically represented as
=>![r = \frac{4.95 *10^{-8} * \sqrt{2} }{4}](/tpl/images/0748/9324/e34a8.png)
=>![r = 1.7500 * 10^{-8} \ cm](/tpl/images/0748/9324/53fd1.png)
