How much sulfur oxide (4) can be obtained by burning 15 g of sulfur?

The sulfur combustion reaction is described by the following chemical reaction equation.

S + O2 = SO2;

When 1 mol of sulfur is burned, 1 mol of its oxide is synthesized.

Let’s calculate the chemical amount of a substance in 15 grams of sulfur.

M S = 32 grams / mol;

N S = 15/32 = 0.469 mol;

The same amount of sulfur oxide will be obtained.

Let’s calculate its volume.

Under normal conditions, one liter of ideal gas assumes a volume of 22.4 liters.

V SO2 = 0.469 x 22.4 = 10.51 liters;
