Question

При проведении в растворе образуется осадок. За каждую минуту образуется 0,85 г осадка. Определи массу осадка (в граммах) в растворе спустя 7 мин после начала реакции.

Answer 1

Ответ:

5,95

Объяснение:

0,85×7=5,95

Answer 2

Calculation of the Mass of Precipitate

To determine the mass of the precipitate formed in the solution after 7 minutes, we can use the given information that 0.85 grams of precipitate is formed every minute.

Given: - Rate of precipitate formation: 0.85 g/minute - Time elapsed: 7 minutes

To calculate the mass of the precipitate formed after 7 minutes, we can multiply the rate of formation by the time elapsed:

Mass of precipitate = Rate of formation × Time elapsed

Mass of precipitate = 0.85 g/minute × 7 minutes

Mass of precipitate = 5.95 grams

Therefore, the mass of the precipitate formed in the solution after 7 minutes is 5.95 grams.
