What is the density of Diet Pepsi?

Do you have a teaspoon of it, a cup, a liter, a gallon? A soda truck full of it? A substance's weight depends upon how much of it you have. Perhaps you wish to know its density, that is, its mass (or weight) per unit volume. As it turns out, the density of Pepsi is just about the same as water, which is one kilogram per liter, or 8.34 pounds per gallon.
