How many moles of sulfur are in Al2 SO4 3?

three moles
One mole of aluminum sulfate contains three moles of sulfur.

How do you calculate the mass percent composition of sulfur in Al2 SO4 3?

Explanation:

  1. \% by mass = mass of componenttotal mass × 100 \%
  2. Mass of 2 Al atoms = 2 Al atoms × 26.98u1Al atom = 53.96 u.
  3. Mass of 3 S atoms = 3 S atoms × 32.06u1S atom = 96.18 u.
  4. Mass of 12 O atoms = 12 O atoms × 16.00u1O atom = 192.0 u.
  5. \% of Al = mass of Altotal mass × 100 \% = 53.96u342.1u × 100 \% =15.77 \%

What is the percent of sulfur in aluminum sulfide?

We used the grams of sulfur coming from that aluminum sulfate compound we placed on the numerator. We divided this by our entire compound. We multiply that by 100 to get our mass percent, which was equal to 28 0.12\%.

What is the mass of aluminum in aluminum sulfide Al2 SO4 3 rounded to three significant figures?

What is the mass \% of aluminum in aluminum sulfate (Al2(SO4)3) rounded to three significant figures? To find the percent composition of Al₂(SO₄)₃, you divide the total mass of each atom by the molecular mass and multiply by 100 \%. = 53.96 u.

How many grams of sulfur are in 3 moles of aluminum sulfate?

Each formula unit of aluminum sulfate has three sulfur atoms, so your 3 moles of aluminum sulfate will contain 9 moles of sulfur atoms. The mass in grams of a mole of sulfur (sulfur’s molar mass) can be found on a periodic table of the elements to be 32 grams per mole. 32 grams per mole x 9 moles = 288 grams of sulfur.
