The equation of the ongoing reaction: S + O2 = SO2.
You do not need to place the coefficients in this equation.
1) Find the amount of oxygen. Consider the reaction equation. One mole of sulfur accounts for one mole of oxygen. This means that the amount of oxygen is also 2 mol.
2) The molar mass of oxygen according to the periodic table: 16.
3) Find the mass of oxygen. For this, the amount of oxygen is multiplied by its molar mass: 16 * 2 * 2 = 64g – the answer.
4) Find the volume of oxygen. To do this, we multiply the amount of oxygen by the molar volume: 16 * 22.4 = 358.4 liters – the answer.
