Answer #1

                  Estimated gold is    8x104 tons

                                           1 Ton = 2000 lb

                                                = 8x104 tons

                                                = 8x104 x 2000 lb

                                     1 lb =453.6 g

                                              = 8x104 x 2000 x453.6 g

                                             = 72576x106 g

Mass og the gold in grams is 72576x106 g
