We have to calculate the mass of sulfur in a 9.0-g mixture of carbon and sulfur that forms a mixture of 24.6 g CO2 and SO2 upon complete combustion.
We will solve this problem through these steps:
Step 1: Write expression for the number of moles of sulfur and carbon in the mixture.
Step 2: Find out the molar masses of CO2 and SO2.
Step 3: Find out the mass of CO2 and SO2 in the product mixture.
Step 4: Calculate the mass of sulfur in the original mixture.
A mixture of carbon and sulfur has a mass of 9.0 g. Complete combustion with excess O2 gives 24.6 g of a mixture of CO2 and SO2.
Find the mass of sulfur in the original mixture.
