* Recipes: Recipes are the most obvious answer. A recipe will specify the exact amounts of each ingredient needed to create a dish.
* Chemical formulas: Chemical formulas represent the exact ratio of elements in a molecule. For example, the formula for water is H2O, meaning there are two hydrogen atoms and one oxygen atom in each water molecule.
* Pre-packaged mixes: Things like cake mix, cookie mix, or powdered drink mixes come with a definite amount of each ingredient pre-measured for convenience.
* Dosage instructions for medication: Medication comes with precise instructions on the amount of each ingredient to take for a specific dosage.
* Some manufactured products: Products like paint, fertilizer, or cleaning solutions often have a defined ratio of ingredients.
It's important to remember that "definite" can be interpreted in different ways. It could mean exactly measured, or it could mean a specific ratio, even if the overall quantity varies.
