The Periodic Table in Figure 11.9 on p. 216 in the textbook. Hint: Remember 1u=1.66x10-27kg. 1 mole= 6.022x1023, which is Avogadro's number

Method I : Atomic mass of gold = 1 96 . 97 uLu = 1 . 6 6 X 10-2 7 Kq( 96 . 9 7 4 = 1. 6 6 X 10 27 x 196 97 kq = 3.269 x 10Kgso weight of one atom = 3 . 26 9 x 10 0 kq3.269 X 1025kq = + atom1...
