The weight of a liter of water can be determined by its density. The density of water is approximately 1 gram per cubic centimeter (g/cm³) or 1000 kilograms per cubic meter (kg/m³). Since there are 1000 milliliters in a liter, we can calculate the weight of a liter of water as follows:
Weight = Volume × Density
Since the volume of 1 liter is equivalent to 1000 cubic centimeters (cm³), we have:
Weight = 1000 cm³ × 1 g/cm³ Weight = 1000 grams
Therefore, a liter of water weighs approximately 1000 grams, which is equivalent to 1 kilogram.
