How many grams of sulfur dioxide does one gram of sulfur in excess oxygen generate?

Answer 1

Ok you have 1 gram of sulfur. Solid sulfur is a molecule with eight sulfur atoms (S8) and has a molar mass of

8 x 32.06 = 256.48 grams per mol

Now the combustion reaction that produces sulfur dioxide is:

S8(s) + 8O2(g) → 8SO2(g)

Molar mass of SO2 is 32 +16+16= 64 grams.

So for each mol of S8 you will get eight moles of SO2 (assuming you have excess oxygen). In terms of mass:

256.48 g of sulfur (1 mol) produces 8x64 g of SO2 (8moles)
then
1 g of sulfur produces X

X= (8x64x1) / 256.48 = 2 grams.

the end.

Answer 2

The reaction equation is as follows:

S + O2 ----------- SO2

Sulfur has an atomic weight of 32
Sulfur dioxide has an atomic weight of 64

The ratio of Sulfur to Sulfur Dioxide is 1:2

So 1 gram of Sulfur would produce 2 grams of Sulfur Dioxide

Answer 3

To solve this problem, you first need a balanced reaction. I'm doing this from memory/best guess, so you'll want to make sure that this part is right. If not, the entire rest of the solution will be incorrect:
S + O2--->SO2

Now you need to know how many grams are in a mole of sulfur and of sulfur dioxide, figure out how many moles of sulfur you have, then figure out how many grams are in the same number of moles of SO2:
S atomic weight (molar mass) = 32.065 (taken from periodic table)
O atomic weight = 15.9994 (ditto)
SO2 molar mass = 64.0638 (32.065 + (2 X 15.9994))

1/32.065 = 0.0312 mol
0.0312 X 64.0638 = 1.9979 g SO2

Answer 4

1 gram S= 1/32.1= 0.03 mol
0.03 mol S in excess oxygen will generate 0.03 mol sulfur dioxide
(sulfur is the limiting factor)
MW of sulfur dioxide = 64.1
therefore 0.03x64.1=1.923g sulfur dioxide

Answer 5

The balanced equation is S + O2 ===> SO2. Start with 1g S. Multiply by 1 g-atom S/32g S. The grams S cancel, leaving gram-atoms of S. Multiply by 1mol SO2/1g-atom S. This comes from the balanced equation. The g-atoms S cancel, leaving moles SO2. Multiply by 64g SO2/1mol SO2. This comes from the molecular weight of SO2: 32 + 2(16) = 64. The moles SO2 cancel, leaving g SO2, whiich is the answer.

Answer 6

don't use yahoo to do your homework for you.

What is the atomic weight of sulfer? What is the atomic weight of oxygen?

and really, that's all you need to answer the question other than some arithmetic. Do your OWN homework.
