What volume of SO2 is formed when 100 g of sulfur is completely burned in oxygen?

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 = 100/32 = 3.125 mol;

Let’s calculate the volume of 3.125 mol of sulfur oxide.

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 = 3.125 x 22.4 = 70 liters;
