Best ResponseYou've already chosen the best response.0#34 For Bismuth (Bi), determine Bi → Atomic # = 83 Atomic mass = 208.98 A. The number of atoms in 0.243 g (7.00 x 10^20 atoms) Bi atoms / Avogadro’s # = 0.243 g / 208.98 g Bi atoms = (0.243 g / 208.98 g) * 6.022 x 10^23 Bi atoms = 7.00 x 10^20 B. The mass of 139 protons (1.631 x 10^22 g)

Best ResponseYou've already chosen the best response.0Hey....Look its simple, Mass of 1 proton=1.6726219 × 1027 kilograms, So, Now,\[136\times1.6726219 × 10^{27} kilograms=2.27\times10^{25}\]
