How many grams are in one cubic centimeter (cc) of water?

One cubic centimeter (cc) of water is equivalent to 1 gram due to the definition of density. The density of water at standard temperature and pressure is approximately 1 gram per cubic centimeter. This means that if you take a volume of water that measures 1 cubic centimeter, it will weigh exactly 1 gram.

This relationship is fundamental in various scientific fields, especially in chemistry and physics, where the measurement of density plays a critical role in calculations related to mass and volume. The choice that states 1 gram accurately reflects this direct and universally accepted conversion, making it the correct answer. Other choices of 0.1 grams, 10 grams, and 100 grams do not represent the mass of water in this specific volume at standard conditions.
