Реторту с порошком свинца и полным объемом 1 литр заполнили воздухом, запаяли и взвесили на
на дисплее отобразилась масса 100,00 граммов. Известно, что масса порошка свинца,
помещенного в реторту, составляет 2,07 граммов. Реторту нагрели до 400°С и свинец целиком
прореагировал с кислородом воздуха с образованием оксида свинца (II). После этого реторту
снова взвесили. Какой вес показали весы?
