The Answer is
.56 moles OR 0.56 moles
0.343 mol

Moles = Mass/ Relative Molecular Mass Aluminum forms Al2 compounds, so the relative molecular mass is 2 * 13 = 26. 856/26 = 32.9 (3sf)
4 moles
33 grams aluminum (1 mole Al/26.98 grams) = 1.2 moles of aluminum ================
1,075 moles of aluminium chloride are obtained.

1,99 grams of aluminum is equal to 0,0737 moles.
Moles = Mass/ Relative Molecular Mass Aluminum forms Al2 compounds, so the relative molecular mass is 2 * 13 = 26. 856/26 = 32.9 (3sf)
10 grams aluminum (1 mole Al/26.98 grams) = 0.37 moles of aluminum ---------------------------------
4 moles
4 moles
33 grams aluminum (1 mole Al/26.98 grams) = 1.2 moles of aluminum ================
The formula shows that 2 aluminum atoms are present in each formula unit, which is, for ionically bonded compound, the alternative to "molecule" for a covalently bonded compound. The formula unit for aluminum itself is generally considered to consist of single atom. Therefore, 0.5 mole of the compound will contain 1.00 moles of aluminum.
1,46 moles of aluminum fluoride contain 35,16848.10e23 atoms.

1,075 moles of aluminium chloride are obtained.
Aluminum sulfide has a molar mass of 150.16 grams per mole. This means there are 0.666 moles present, or 4.01 E23 molecules. Each molecule of Al2S3 has 2 aluminum atoms, so there are 8.02 E23 atoms of aluminum present.
