Ответ:

240 гр. раствора

Объяснение:

х количество раствора содержит 120 гр азотной кислоты и эта масса составляет 50 % от всей массы раствора

значит если у нас :

50% - 120 гр азотной кислоты

100% - х = 240 гр. раствора

где 100% это общая масса всего сосуда(раствора) а 50%(т.е половина) это азотная кислота с массой 120гр.

раствор - смесь или состав в который входят растворитель и растворимое вещество)

где растворитель - вода

растворимое вещество - любое соединение
