Question

Calculate the mass of sulphur dioxide produced by burning 16 gram of carbon sulphur in excess of oxygen in contact process

Answer 1

Answer

Quantity of sulfur = 16g

Moles S = 16 g / 32 g/mol = 0.5  

Moles O2 needed = 0.5  

Mass of O2 = 0.5 mol x 32 g/mol = 16 g  

Moles SO2 produced = 0.5  

Mass SO2 = 0.5 mol x 64 g/mol = 32 g

Therefore the atomic mass of so2 -

32+(16 × 2)

= 64

If 16g of sulfur is used, then the tomic mass of so2

= 16+(16 × 2)

= 48

Thus, the mass of sulfur dioxide is 48g.
