What is the mass of 3 moles of aluminum oxide?

102.0 g/mol
Aluminum oxide is Al2O3. = 102.0 g/mol The molar mass of a compound is just the mass of one mole of the compound. Add up the molar mass of each and every atom in a formula unit of the compound.

What is the mass of moles of aluminium atoms atomic mass of aluminium is equal to 27?

(Atomic mass of Al = 27 u) The atomic mass of aluminium is given to be 27u. This means that 1 mole of aluminium atoms has a mass of 27 grams. Thus, the mass of 4 moles of aluminium atoms is 108 grams.

What is the relative atomic mass of aluminum?

26.981539 u
Aluminium/Atomic mass

What is the mass of 4 moles of aluminium?

Mass of 4 moles of aluminium atoms = (27 x 4) = 108 g.

How many moles of aluminum are in aluminum oxide?

Aluminium oxide has the formula AlO. This has a formula mass of 101.96 g mol. That means that 12 g of AlO contain 12 g / 101.96 g mol = 0.118 moles of AlO. Each AlO formula unit contains two Al ions, so there are 2 x 0.118 mol = 0.235 moles of Al ions.

What is mole of Aluminium?
