6.(0-2) Black powder was invented in China in the 9th century. It was used as an explosive with propelling properties. Today it is used in fireworks, model rocket engines, and replica black powder weapons. Black powder consists of potassium nitrate (potassium nitrate, KN03), charcoal and sulfur. A variety of chemical reactions take place when this mixture is exploded. One of these is shown below. 2KNO, +S+ 30 → K, S+N, ↑+3C0, 1 Knowing that carbon makes up 15% of the black powder, calculate the total volume of gases (under normal conditions) released when 0.1 kg of black powder explodes. Assume that only the chemical reaction given above occurs.
