Question

. Calculate the mass of sulfur dioxide
produced by burning 16 g of sulfur in
excess of oxygen in contact process.
(Average atomic mass : S = 32 u,
0 = 16 )
​

Answer 1

Answer:

Moles S = 16 g/32 g/mol = 0.5 Moles 02 needed = 0.5 mass 02 = 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
