Проблема разбавления стандартного раствора

Thread Content

У меня есть стандартные растворы ионов фтора концентрацией 1000 ppm и 10 ppm. Теперь я хочу приготовить растворы с концентрацией 1 ppm или 20 ppm. Подскажите, пожалуйста, как это сделать? Буду благодарен, если вы подробно опишете все шаги! Большое спасибо!
