1. Let’s compose the equation of the chemical reaction of sulfur combustion:
S + O2 = SO2
According to the equation: all substances are taken in an amount of 1 mol:
find the mass of sulfur by the formula:
m (S) = n * M = 1 mol * 32 g / mol = 32 g
find the volume of sulfur oxide (IV) by the formula:
V (SO2) = Vm * n = 22.4 L / mol * 1 mol = 22.4 L
2. Let’s calculate the volume of sulfur oxide (IV), making the proportion:
16 g S – xl SO2
32 g S – 22.4 l SO2
Hence, x = 16 * 22.4 / 32 = 11.2 l
Answer: V (SO2) = 11.2 liters.
