What is the maximum mass of aluminium which can be obtained from 240g of Aluminium oxide Al2O3?

The molar mass of Al2O3 is 101.96 g/mole. We can divide the mass of our sample by the molar mass of the material to get the number of moles Al2O3. Now, use the molar mass of aluminum (26.98 g/mole) to calculate the total mass of aluminum in the sample. So, 127 grams of our 240 g sample is aluminum!

What is the maximum mass of aluminium which can be obtained from 204 gram of Aluminium oxide?

(204 g)/(101.96 g/mol) = 2.001 mol. 2(2.001) = 4.002 moles of aluminium in the sample. Then there are (4.002 mol)(26.98 g/mol) = 107.97 g of Al. Since the given mass has only 3 significant figures, round this answer to 108 g.

What mass of aluminum oxide is produced when 135g of aluminum is burned in oxygen?

5 moles
Calculate the mass of aluminium oxide formed when 135 g of aluminium is burned in air. 4Al + 3O2 → 2Al2O3 1. Number of moles of Al = mass/Mr 135/27 = 5 moles.

The maximum mass of aluminum oxide that can be produced is the amount the limiting reagent can produce. Mass of aluminum oxide produced by 30.4 g Al Determine moles Al by dividing its given mass by its molar mass (26.982 g/mol). Since molar mass is a fraction (g mol), we can divide by multiplying by the reciprocal of the molar mass (mol g).

How many moles are there in 204 grams of aluminum oxide?

The molar mass of aluminium is 26.98 g/mol; the molar mass of (atomic) oxygen is 16.00 g/mol. 1 mole of Al₂O₃ therefore has a mass of 2(26.98) + 3(16.00) = 101.96 g. Divide this into the given mass, to find the number of moles here: (204 g)/(101.96 g/mol) = 2.001 mol. There are 2 moles…

How do you find the mass of a mole of aluminum?

Answer Wiki. The molar mass of aluminium is 26.98 g/mol; the molar mass of (atomic) oxygen is 16.00 g/mol. 1 mole of Al₂O₃ therefore has a mass of 2(26.98) + 3(16.00) = 101.96 g. Divide this into the given mass, to find the number of moles here: (204 g)/(101.96 g/mol) = 2.001 mol. 2(2.001) = 4.002 moles of aluminium in the sample.
