0.92 moles Al2(CrO4)3 (374.98 grams/1 mole Al2(CrO4)3)
= 345 grams Al2(CrO4)3 ( might call it 350 grams for sigi figi reasons )
152.10 g/mol
The atomic mass of Aluminum Sulfide is 150.158 g/mol
I'm assuming you mean 13g of Aluminum and 18g of Chlorine Atomic mass of Al = 27g/mol number of moles = mass / atomic mass = 13g / 27g/mol = 0.481mol Molecular mass of Cl2 = 2(35.5) = 71g/mol number of moles = mass / atomic mass = 18g / 71g/mol = 0.254mol The balanced equation for reaction between Aluminum and Chlorine: 2Al + 3Cl2 --> 2AlCl3 The ratio of Al to Cl2 is 2:3 and there's only 0.254mol of Cl2 therefore it's completely reacted and Al is in excess. The ratio of Cl2 to AlCl3 is 3:2 and 0.254mol of Cl2 so there's (0.254mol x 2/3) = 0.169mol of AlCl3 formed. Molecular mass of AlCl3 : 27 + 3(35.5) = 133.5g/mol mass = number of moles x molecular mass = 0.169mol x 133.5g/mol = 22.56g of AlCl3

Aluminum Oxide is Al2O3 and Al = 27 and oxygen =16 so the molar mass is 102 g/mol Al2O33.75 mol Al ~ 3.75/2 mol Al2O3 ~ (3.75/2)mol * 102 g/mol = 191.25 = 191 gram Al2O3
Molar Mass of Al: 2(27.0g/mol) = 54.0g/mol Molar Mass of O: 3(16.0g/mol) = 48.0g/mol Molar Mass of compound: 102.0g.mol (54.0g/mol / 102.0g/mol) x 100% = 52.9%
Molar Mass of Al: 2(27.0g/mol) = 54.0g/mol Molar Mass of O: 3(16.0g/mol) = 48.0g/mol Molar Mass of compound: 102.0g.mol (54.0g/mol / 102.0g/mol) x 100% = 52.9%

The atomic mass of Aluminum Sulfide is 150.158 g/mol
For this you need the atomic mass of Al. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.00 moles Al × (27.0 grams) = 54.0 grams Al
As the periodic table of Elements states, Al has a Molar Mass (Grams/Mole) of 27.0g/mol. So 3 mols of Al mass is the same as 3 times 27.0g/mol. So, the equation is as follows: 3mols x 27.0g/mol = 81.0g. The reason on why it ends with grams is because the unit of moles in 3 will cancel out with the unit of mols in 27.0g.
Each compound has a different molar mass.
