Ответ:

При реакции кремневой кислоты (SiO2) с гидроксидом алюминия (Al(OH)3) образуется соль алюминия - кремнистый силикат (Al2Si2O5(OH)4). Для того, чтобы вычислить массовые доли каждого элемента в этой соли, необходимо узнать массу каждого элемента в этой соли.

Масса алюминия (Al) равна 27 г/моль, масса кислорода (O) равна 16 г/моль, масса углерода (C) равна 12 г/моль, масса кремния (Si) равна 28 г/моль.
