Calculate the amount of oxygen required to burn 54g of sulfur.
August 1, 2021 | education
| The combustion reaction of sulfur is described by the following chemical reaction equation:
S + O2 = SO2;
One mole of sulfur reacts with one mole of oxygen to form one mole of sulfur dioxide.
Let’s determine the amount of substance in 54 grams of sulfur.
M S = 32 grams / mol;
N S = 54/32 = 1.6875 mol;
Therefore, the reaction consumed 1.6875 mol of oxygen.
Under normal conditions, one mole of ideal gas takes up a volume of 22.4 liters.
V O2 = 1.6875 x 22.4 = 37.8 liters;
