# At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml,
1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft
# At 4°C pure water has a specific gravity of 1. ( Some reference the s.g. base temperature as 60F.)
# Water is essential for life. Most animals and plants contain more than 60 % water by volume.
# More than 70 % of the Earth's surface is covered with about 1.36 billion cubic kilometers of water / ice
# The density of pure water is a constant at a particular temperature, and does not depend on the size of the sample. That is, it is an intensive property. The density of water varies with temperature and impurities.
# Water is the only substance on Earth that exists in all three physical states of matter: solid, liquid and gas.
# When water freezes it expands rapidly adding about 9 % by volume. Fresh water has a maximum density at around 4° Celsius. Water is the only substance where the maximum density does not occur when solidified. As ice is lighter than water, it floats.
# Water has a very simple atomic structure. This structure consists of two hydrogen atoms bonded to one oxygen atom - H2O

How many litres of water do you have?
The number of litres of water is about the same as the mass of water in kilograms.

The mass depends on the amount present.
The density is 62.4 lb/cu ft.

assuming you use the value 1.00794 grams for Hydrogen, and 15.9994 grams for Oxygen, the mass of water would be 18.01528 g.
