Question

Число атомов в формульной единице сульфата хрома 3?

Answer 1

$Cr_2(SO_4)_3$

Всего атомов - 17(2 Хрома,3 Сульфура,12 Оксигена)

 

 

 

 

Answer 2

Number of Atoms in the Chemical Formula for Chromium Sulfate

The chemical formula for chromium sulfate is Cr2(SO4)3. This formula indicates that there are 2 chromium atoms and 3 sulfate ions in each formula unit.

Therefore, the total number of atoms in the formula unit of chromium sulfate is: - 2 chromium atoms - 3 * 4 = 12 oxygen atoms from the sulfate ions - 3 * 1 = 3 sulfur atoms from the sulfate ions

So, the total number of atoms in the formula unit of chromium sulfate is 2 + 12 + 3 = 17.
