What volume of sulfur oxide 4 is formed when burning 8g of sulfur?

The sulfur combustion reaction is described by the following chemical reaction equation.
S + O2 = SO2;
From one mole of sulfur, one mole of its oxide is formed.
Let’s find the amount of substance in 8 grams of sulfur.
To do this, we divide the mass of sulfur by its molar mass.
M S = 32 grams / mol;
The amount of substance will be:
N S = 8/32 = 0.25 mol;
