Answer 1

Al2(SO4)3

Mэкв=М(Al2(SO4)3)/(2*3)=57 гр/моль.

 

Answer 2

Molar Mass of Aluminum Sulfate Equivalent

The molar mass of aluminum sulfate equivalent can be calculated using the chemical formula Al2(SO4)3. The molar mass is the sum of the atomic masses of all the atoms in the compound.

The molar mass of aluminum sulfate equivalent (Al2(SO4)3) is calculated as follows:

- The atomic mass of aluminum (Al) is 27 g/mol. - The atomic mass of sulfur (S) is 32 g/mol. - The atomic mass of oxygen (O) is 16 g/mol.

Using the chemical formula Al2(SO4)3, we can calculate the molar mass as follows:

2 atoms of aluminum (Al) = 27 g/mol * 2 = 54 g/mol 3 molecules of sulfate (SO4) = (32 g/mol + 16 g/mol * 4) * 3 = 96 g/mol * 3 = 288 g/mol

Therefore, the molar mass of aluminum sulfate equivalent (Al2(SO4)3) is: 54 g/mol (Al) + 288 g/mol (SO4) = 342 g/mol.

So, the molar mass of aluminum sulfate equivalent (Al2(SO4)3) is 342 g/mol.
