The number of atoms in AlCl3 will vary depending on how much AlCl3 you have. If you have one single molecule (formula unit) of AlCl3, then there are 4 atoms. If you have 10 molecules (formula units) then there are 40 atoms, and so on.
The compound is aluminum chloride (AlCl3). In this compound, there are three aluminum atoms and nine chlorine atoms (3 times as many as aluminum atoms).
Aluminium trichloride has 4 atoms in the formula unit.
The gram atomic mass of aluminium is 26.9815, and the gram atomic mass of chlorine is 35.453. The formula shows that there are three chlorine atoms for each aluminium atom in the compound. Therefore, the mass fraction of aluminium in the compound is 26.9815/[26.9815 + 3*(35.453)] or about 0.20235004, and the grams of aluminium present are 20.24, to the justified number of significant digits. _______________________________________ *An exact integer.
AlCl3 is the correct formula as the valency of aluminium and chlorine are 3 and 1 respectively.
AlCl3 1 Aluminium to 3 Chlorine atoms 1:3
There are 3 atoms of chlorine in aluminum chloride (AlCl3).
The ratio in aluminum chloride is 1:3 aluminum to chloride ( AlCl3 or Al2Cl6 )
The compound is aluminum chloride (AlCl3). In this compound, there are three aluminum atoms and nine chlorine atoms (3 times as many as aluminum atoms).
There are 6 chlorine atoms on the products side of the reaction, in the form of 2 molecules of AlCl3. Each molecule of AlCl3 contains 3 chlorine atoms.
The formula would be AlCl3, which is aluminum chloride.
For this problem, the atomic mass is required. Take the mass in grams and divide it by the atomic mass. Then multiply it by Avogadro's constant, 6.02 × 1023. AlCl3= 133.5 grams10.5 grams Cu / (133.5 grams) × (6.02 × 1023 atoms) = 4.73 × 1022 atoms
1 mol of AlCl3 has mass 133.5 g and has 3 mol Cl- atoms so 400.5 g AlCl3 means 3 mol AlCl3 which means 9 mol Cl- atoms. So Ans = 9 X 6.022 X 1023 = 5.4198 X 1024 Cl- atoms
Aluminium trichloride has 4 atoms in the formula unit.
Aluminium chloride (AlCl3) has one aluminium atom (Al) and three chlorine atoms (Cl). The chemical formula AlCl3 indicates that there is one aluminium atom bonded to three chlorine atoms in the compound.
Count them :- Al = 1 Cl = 3 that makes 4 atoms
Aluminum chloride has the chemical formula AlCl3. This means one aluminum atom is bonded to three chlorine atoms. Therefore, in one molecule of aluminum chloride, there are a total of 4 atoms (1 aluminum atom + 3 chlorine atoms).
No, AlCl3 does not follow the octet rule. Aluminum typically forms compounds where it only has 6 electrons in its outer shell, such as in AlCl3 where it forms 3 bonds with chlorine atoms.
