What is density of water in g ml? What is the mass of a 53.0 mL volume of liquid, which has a density of 2.12 g/mL? What is the mass of 25 cm3 of pure water? What is the mass of 53.0 ml of a liquid having a known density of 2.12 g/ml ?
the density of water is very close to 1 g/cm3, which is why that value is used in all but the most exact density calculations. It's not until the temperature is very extreme in one direction or another (close to freezing or boiling), that the temperature of water changes enough that ...
Kruszelnicki said that experiments conducted by Australia’s CSIRO (the Commonwealth Scientific and Industrial Research Organization) showed that with model ships if enough bubbles are coming to the surface, the density of water is reduced. So, Kruszelnicki said there’s a slight possibility that ...
2. Water is a liquid at room temperature and has a relatively high frozen point.3. The nutrients in whatever falling into the ocean will quickly become available to other living creatures.4. The density of pure water is 1000 kg/m3,meaning that one cubic metre of water weighs for one ...
