What volume of sulfur (IV) oxide is formed when burning sulfur with a mass of 128g?
June 20, 2021 | education
| The reaction of sulfur with oxygen occurs in accordance with the following chemical reaction equation:
S + O2 = SO2;
For oxidation of 1 mole of sulfur, 1 mole of oxygen is required. In this case, 1 mol of its oxide is synthesized.
Let’s find the amount of sulfur.
M S = 32 grams / mol;
N S = 128/32 = 4 mol;
Let’s calculate the volume of 4 mol of sulfur dioxide.
One mole of gas under normal conditions fills a volume of 22.4 liters.
The volume of sulfur oxide will be equal to:
V SO2 = 4 x 22.4 = 89.6 liters;
