The molar mass of aluminum nitride (AlN) is 40.99 g/mol for aluminum and 14.01 g/mol for nitrogen. Adding these together gives a molar mass of 74.0 g/mol for aluminum nitride.

To calculate the molar mass of aluminum sulfate (Al₂(SO₄)₃), we need to sum the masses of its constituent elements. Aluminum (Al) has a molar mass of approximately 27 g/mol, sulfur (S) about 32 g/mol, and oxygen (O) around 16 g/mol. The formula contains 2 aluminum atoms, 3 sulfur atoms, and 12 oxygen atoms: [ (2 \times 27) + (3 \times 32) + (12 \times 16) = 54 + 96 + 192 = 342 \text{ g/mol} ] Thus, the molar mass of aluminum sulfate is approximately 342 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

To find the moles of carbon in aluminum acetate, first calculate the molar mass of aluminum acetate (Al(CH3COO)3). The molar mass of aluminum acetate is 204.12 g/mol. The molar mass of carbon is 12 g/mol. Calculate the ratio of carbon to aluminum acetate: 12 g/mol (carbon) / 204.12 g/mol (aluminum acetate) = 0.0587 mol of carbon in 1 mol of aluminum acetate. Then, calculate the moles of carbon in 35 g of aluminum acetate: 35 g / 204.12 g/mol * 0.0587 mol = 0.01 mol of carbon.

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
To calculate the number of aluminum atoms in 2.78g of aluminum, you first need to convert the mass to moles using the molar mass of aluminum (26.98 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to determine the number of atoms. The calculation would be: (2.78g Al) / (26.98 g/mol) * (6.022 x 10^23 atoms/mol).
The molecular formula of aluminum sulfate is Al2(SO4)3. To calculate the molecular mass, multiply the atomic mass of each element by the number of atoms present in the formula and then add them up. The molecular mass of aluminum sulfate is 342.15 g/mol.

To find how many grams of aluminum are in 25.0g of aluminum oxide, first, determine the molar mass of aluminum oxide (Al2O3), which is 101.96 g/mol. Next, calculate the molar mass of aluminum (Al), which is 26.98 g/mol. Then, set up a ratio using the molar masses to find the amount of aluminum in 25.0g of aluminum oxide: (2 mol Al / 1 mol Al2O3) x (26.98 g Al / 101.96 g Al2O3) x 25.0g Al2O3 = 6.63g of aluminum.

The molar mass of aluminum nitride (AlN) is 40.99 g/mol for aluminum and 14.01 g/mol for nitrogen. Adding these together gives a molar mass of 74.0 g/mol for aluminum nitride.
The balanced chemical equation for the reaction is 4Al + 3O2 -> 2Al2O3. Since the molar ratio between aluminum and oxygen is 4:3, aluminum is the limiting reagent. Therefore, the theoretical yield of aluminum oxide is based on the 3.00 mol of aluminum. Using stoichiometry, the theoretical yield of aluminum oxide would be 3.00 mol of Al * (2 mol Al2O3 / 4 mol Al) = 1.50 mol of Al2O3.
