Calculate the number of moles of alumunium sulfer, oxygen atoms in 9.00 moles of Alumunium sulfate, Al2(SO4)3?

To calculate the number of moles of aluminum sulfate and the number of oxygen atoms in 9.00 moles of Al2(SO4)3, we'll use the mole ratios from the chemical formula.

The chemical formula Al2(SO4)3 tells us that there are 2 moles of aluminum (Al) atoms, 3 moles of sulfur (S) atoms, and 12 moles of oxygen (O) atoms in 1 mole of aluminum sulfate.

Number of moles of Al2(SO4)3 = 9.00 moles

Number of moles of Al = 2 * 9.00 = 18.00 moles
Number of moles of S = 3 * 9.00 = 27.00 moles
Number of moles of O = 12 * 9.00 = 108.00 moles

Therefore, in 9.00 moles of aluminum sulfate, there would be:
- 18.00 moles of aluminum (Al) atoms
- 27.00 moles of sulfur (S) atoms
- 108.00 moles of oxygen (O) atoms.

To calculate the number of moles of aluminum sulfate, Al2(SO4)3, we will use the given information that there are 9.00 moles of aluminum sulfate.

From the chemical formula Al2(SO4)3, we can determine the number of moles of each element in one mole of aluminum sulfate:
- Each mole of aluminum sulfate contains 2 moles of aluminum (Al2).
- Each mole of aluminum sulfate contains 3 moles of sulfur (S).
- Each mole of aluminum sulfate contains 12 moles of oxygen (O).

To find the number of moles of aluminum (Al), sulfur (S), and oxygen (O) atoms in 9.00 moles of aluminum sulfate, we multiply the respective ratios by the number of moles of aluminum sulfate:

Aluminum (Al):
Number of moles of Al = 9.00 moles of Al2(SO4)3 × (2 moles of Al / 1 mole of Al2(SO4)3)
Number of moles of Al = 18.00 moles of Al

Sulfur (S):
Number of moles of S = 9.00 moles of Al2(SO4)3 × (3 moles of S / 1 mole of Al2(SO4)3)
Number of moles of S = 27.00 moles of S

Oxygen (O):
Number of moles of O = 9.00 moles of Al2(SO4)3 × (12 moles of O / 1 mole of Al2(SO4)3)
Number of moles of O = 108.00 moles of O

Therefore, in 9.00 moles of aluminum sulfate, there are:
- 18.00 moles of aluminum atoms (Al)
- 27.00 moles of sulfur atoms (S)
- 108.00 moles of oxygen atoms (O)

There are 2 moles Al atoms, 3 moles S atoms, and 12 moles O atoms in 1 mole of Al2(SO4)3.

Therefore, in 9 moles Al2(SO4)3, there must be 9x2, 9x3 etc.
