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

How many grams of aluminium are contained in 100.0 g of aluminum chloride AlCl3?

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.

How many grams of aluminum chloride are produced when 18 grams of aluminum are reacted with an excess of hydrochloride acid?

The empirical formula for aluminum chloride is AlCl3, and its gram formula mass is 133.34. The formula shows that each formula unit contains one aluminum atom, and the the gram atomic mass of aluminum is 26.9815. Therefore, 18(133.34/26.9815) or 89 grams, to the justified number of significant digits, of aluminum chloride will be produced.


Does 1 gram sample of iron has a small number of atoms?

No, even a small 1 gram sample of iron contains a very large number of iron atoms. Iron has a molar mass of 55.85 g/mol, so 1 gram of iron would contain about ( \frac{1}{55.85} ) moles of iron atoms, which is approximately ( 6 \times 10^{22} ) atoms.


What is the total number of moles present in a 52.0 gram sample of NaN3 gram formula mass equals 65.0 mole?

To calculate the total number of moles in the 52.0 gram sample of NaN3, divide the given mass by the molar mass of NaN3. First, determine the molar mass of NaN3 by summing the atomic masses of its elements (sodium, nitrogen, and three times the atomic mass of nitrogen). Then, divide the mass of the sample by the molar mass of NaN3 to find the number of moles.


How many molecules of H2(g) are there in a 21.25 gram sample?

To calculate the number of molecules, you first need to determine the number of moles of H2 in the 21.25 gram sample using the molar mass of H2 (2 grams/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.


Which sample contains the same number of atoms as a gram atomic mass of he?

A gram atomic mass of helium (He) contains the same number of atoms as 1 mole of helium. Since 1 mole of any substance contains approximately 6.022 x 10^23 atoms, a sample of helium with a gram atomic mass would contain that same number of atoms.


How many moles of ammonium ions does a 22.5 gram sample of ammonium carbonate?

To calculate the number of moles of ammonium ions in a 22.5 gram sample of ammonium carbonate, you need to first determine the molar mass of ammonium carbonate. Then, divide the given mass by the molar mass to find the number of moles. After that, since there are 2 ammonium ions in one molecule of ammonium carbonate, you will need to multiply the result by 2 to determine the number of moles of ammonium ions.
