Question

Розрахуйте масові частки елементів у сполуці AlCl3.

Answer 1

Ответ:

Mr(AlCl3)=27+3*35.5=133.5

W(Al)=27/133.5=0.2=20%

W(Cl3)=3*35.5/133.5=0.80=80%

Объяснение:

Answer 2

Відповідь:Ar(AlCl3):Ar(Al)27x1+Ar(Cl)35x3=132

Calculating the Molar Mass of AlCl3

To calculate the molar mass of AlCl3, we need to consider the atomic masses of aluminum (Al) and chlorine (Cl) and then sum them up.

The molar mass of aluminum (Al) is approximately 26.98 g/mol, and the molar mass of chlorine (Cl) is approximately 35.45 g/mol.

So, the molar mass of AlCl3 can be calculated as follows: Molar mass of AlCl3 = (1 * molar mass of Al) + (3 * molar mass of Cl)

Molar mass of AlCl3 = (1 * 26.98 g/mol) + (3 * 35.45 g/mol) Molar mass of AlCl3 = 26.98 g/mol + 106.35 g/mol Molar mass of AlCl3 = 133.33 g/mol

The molar mass of AlCl3 is approximately 133.33 g/mol.
