how many of moles of oxygen atoms are in .02 moles of aluminum sulfate
aluminum sulfate is Al2(SO4)3
so the ratio of O to Al is 12/2 = 6:1
so .02 moles of Al2(SO4)3 means 0.02*6 = 0.12 moles of oxygen atoms
oops! 0.02 moles Al2(SO4)3 x (12 mols O atoms/1 mol Al2(SO4)3 molecules) = 0.24 moles O atoms.
To determine the number of moles of oxygen atoms in 0.02 moles of aluminum sulfate, we need to first understand the chemical formula of aluminum sulfate.
The formula for aluminum sulfate is Al₂(SO₄)₃. This means that the compound consists of two aluminum atoms (Al), three sulfate ions (SO₄), and a total of twelve oxygen atoms (O) in the sulfate ions.
To calculate the number of moles of oxygen atoms, we need to multiply the number of moles of aluminum sulfate by the number of oxygen atoms per mole of aluminum sulfate.
Number of moles of oxygen atoms = Number of moles of aluminum sulfate × Number of oxygen atoms per mole of aluminum sulfate
In this case, the number of moles of aluminum sulfate is 0.02 moles, and the number of oxygen atoms per mole of aluminum sulfate is 12.
Number of moles of oxygen atoms = 0.02 moles × 12
Number of moles of oxygen atoms = 0.24 moles
Therefore, there are 0.24 moles of oxygen atoms in 0.02 moles of aluminum sulfate.
