What is the density of water in g/mL? What does that mean?
The Correct Answer and Explanation is:
The density of water is 1.0 g/mL at standard temperature and pressure (typically around 4°C and 1 atmosphere of pressure).
What does that mean?
Density is a measure of how much mass is contained in a given volume. When we say the density of water is 1.0 gram per milliliter (g/mL), it means that each milliliter of water has a mass of 1.0 gram. In other words, if you were to take a small measuring spoon or a syringe and collect exactly 1 milliliter of water, it would weigh exactly 1 gram.
This relationship holds true because of the unique molecular arrangement of water. Water molecules are tightly packed together in liquid form, but not so tightly that they become a solid. The result is a balance that gives water its typical density of 1.0 g/mL.
This property is very useful in science and everyday life. For instance, since the density of water is 1.0 g/mL, it is often used as a reference point when comparing the density of other substances. Substances with a density greater than 1.0 g/mL will sink in water, while those with a density less than 1.0 g/mL will float.
It also means that you can easily convert between grams and milliliters for water. For example, 250 mL of water has a mass of 250 grams. This 1-to-1 ratio simplifies many calculations in chemistry and cooking.
In summary, the density of water being 1.0 g/mL tells us that the mass and volume of water are numerically equal in these units, making it a convenient standard in measurements involving liquids.
