Determine the mass (in grams) of sulfur that must be taken for the reaction with oxygen

Determine the mass (in grams) of sulfur that must be taken for the reaction with oxygen to form 3.2 g of sulfur oxide (4)

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. This is due to the fact that the oxide molecule contains 1 sulfur atom.

Let’s calculate the chemical amount of a substance that is in 3.2 grams of sulfur oxide.

M SO2 = 32 + 16 x 2 = 64 grams / mol;

N SO2 = 3.2 / 64 = 0.05 mol;

Calculate the weight of 0.05 mol of sulfur.

M S = 32 grams / mol;

The weight of the sulfur will be:

m S = 32 x 0.05 = 1.6 grams;
