Potassium nitrate has many uses. It was used as a preservative in salted meat until very recently. It is a major constituent of gunpowder (blackpowder), fireworks, and solid rocket propellant. But perhaps its current most widespread use is as a source of fixed nitrogen in fertilizers and tree stump removers. How many grams of nitrogen are found in 50.0 g of potassium nitrate?...
