600 views
The density of water is approximately 1,000 mg/mL at standard temperature (4°C). This means that each milliliter of water weighs about one gram. This property is crucial for various applications, including calibrating laboratory equipment, designing water-related machinery, and performing scientific calculations. Keep in mind that the density can slightly vary with temperature and impurities, so it's essential to consider these factors in precise applications.
