How much does 500 cc weigh?

500 cubic centimeters (cc) of water weighs 500 grams, which is equivalent to 0.5 kilograms. This is because the density of water at room temperature and pressure is 1 gram per cubic centimeter. However, it's important to note that the weight of 500 cc of a substance can vary depending on the substance's density. For example, 500 cc of a denser substance like mercury would weigh more than 500 cc of a less dense substance like oil.
