Baking Grandma's Cake
In chemistry, the law of definite proportions dictates that any chemical compound always contains the same elements in the exact same proportions by mass. A good example is water because it will always have the same composition regardless of the amount you have.
Let’s say you want to bake your grandmother’s famous chocolate cake using her recipe. It calls for proportions such as 1 cup of flour to 1/2 cup of water, and 3 cups of sugar to 2 cups chopped chocolate chips.
