How many moles og Al are in 2.16 mol of Al2O3?
so you find the ratio of Aluminum to Oxygenin this case it is 2:3and then because the total mole is 2.16for aluminum:2.16/5*2 = 0.864for oxygen:2.16/5*3 = 1.296hope this helped :D
What is the number of moles of Al2O3 that are produced when 0.60 mol of Fe is produced show how you got it?
Well, honey, it's simple math. The balanced chemical equation tells us that 4 moles of Al2O3 are produced for every 3 moles of Fe. So if you start with 0.60 mol of Fe, you just set up a simple ratio and find that you'll produce 0.80 mol of Al2O3. Easy peasy lemon squeezy!
How many atoms in 1 mol of chlorine?
There are approximately 6.022 x 10^23 atoms in 1 mol of chlorine, according to Avogadro's number.
How many aluminum atoms are in 291.257 grams of Al2O3?
The gram molecular mass of Al2O3 is 2(26.982) + 3 (15.999) = 101.96. Therefore, the number of moles of Al2O3 is 291.257/101.96 = 2.857 moles. Each mole contains two moles of aluminum atoms; therefore the number of aluminum atoms in this mass equals 2 X 2.857 X 6.022 X 1023 = 3.4410 X 1024 atoms.
How many oxygen atoms are there in 0.5 mol of CO2?
There are 1 mol of oxygen atoms in 1 mol of CO2. Therefore, in 0.5 mol of CO2, there are 0.5 mol of oxygen atoms. Number of molecules = 0.5*6.022 *10^23 ≈ 3.011 *10^23 molecules

How many atoms of phosphorus are in 3.30 mol of copper (ll) phosphate?
There are 1 mol of phosphorus atoms in 1 mol of copper (II) phosphate. Therefore, in 3.30 mol of copper (II) phosphate, there are 3.30 mol of phosphorus atoms, which is equivalent to 3.30 x 6.022 x 10^23 = 1.97 x 10^24 atoms of phosphorus.
How many grams of alcl3 are produced from with 8.0 moles of al2o3. 6cl2 plus 2al2o3 equals 3o2 plus 4alcl3 equals?
8 mol x (4 mol / 2 mol) x 133.5 g / 1 mol = 2136 grams
How many grams of aluminum are in 25.0g of aluminum oxide?
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.
How many atoms of sodium are in 2.35 mol of NaCl?
In NaCl, the ratio of sodium to chloride atoms is 1:1. Therefore, in 2.35 mol of NaCl, there are 2.35 mol of sodium atoms. To find the number of sodium atoms, you would multiply the number of moles by Avogadro's number (6.022 x 10^23).
How many moles of atoms are there in 2.65g?
2.65g(1 mol/6.022*1022atoms)
Calculate the number of grams of Al in 371 g of Al2O3?
To calculate the number of grams of Al in 371 g of Al2O3, you first need to determine the molar mass of Al2O3 (102 g/mol). Then, calculate the molar mass of Al (27 g/mol). From the chemical formula Al2O3, you can see that there are 2 moles of Al for every 1 mole of Al2O3. Therefore, by using these ratios, you can determine that there are 162 g of Al in 371 g of Al2O3.
