Объяснение:

   460 г                                     Х г

   2Na          +       Cl2     =      2NaCl

n=2 моль                             n=2 моль

М=23 г/моль                       М = 58,5 г/моль

m=46 г                                  m=117 г

460 г  Na   -   Х г   NaCl

46 г  Na    -  117 г  NaCl

m(NaCl) = 460 * 117 / 46 = 1 кг 170 г

Он кормит белок шишками,
За стол садится с мишками,
С пушистыми зайчишками
Да с мышками-норушками!
Он делится орешками
С косулями, с олешками,
С кротами кропотливыми,
С бобрятами смешливыми.
