How much oxygen and how much air will be required to burn 1 kg sulfur

Question

Accepted Answer

To burn 1 kg of sulfur, 2.66 kg of oxygen and 8.66 kg of air will be required.

Sulfur requires oxygen to burn and forms sulfur dioxide (SO2) gas.
The balanced chemical equation for the combustion of sulfur is: S + O2 -> SO2
The molar mass of sulfur is 32 g/mol, and the molar mass of oxygen is 32 g/mol.
The molar mass of air is approximately 29 g/mol.
Using stoichiometry, we can determine the amount of oxygen and air required.
For every 1 mole of sulfur, 1 mole of oxygen is required.
Therefore, for 1 kg (1000 g) of sulfur, 1000 g / 32 g/mol = 31.25 moles of sulfur are present.
Thus, 31.25 moles of oxygen are required, which is equal to 31.25 moles x 32 g/mol = 1000 g of oxygen.
Since air is approximately 21% oxygen by volume, we can calculate the amount of air required.
The mass of air required is 1000 g / 0.21 = 4761.9 g (approximately 4.76 kg).
