Question

Sulphur burns in oxygen to give sulphur dioxide. If 16 g. of sulphur burns in ‘x’ cc. of oxygen, calculate the amount of potassium nitrate which must be heated to produce V cc. of oxygen. [S = 32, K = 39, N = 14, O = 16].

Answer 1

32 g of sulphur require O₂ obtained from KNO₃ = 202 g

16 g of sulphur will require O₂ produced from KNO₃
