                                For instance, medical-grade normal saline contains a precise 9 grams of salt per liter of water, but the amount of salt you need for a liter varies drastically depending on the application, from cooking to medical solutions. This variation highlights that there is no single answer, and the correct quantity is entirely dependent on your specific purpose.
