What is the mass of 2.7 L of water?

The mass of water can be calculated using its density, which is approximately 1 gram per milliliter (g/mL) at room temperature. Since there are 1,000 milliliters in a liter, 2.7 liters of water is equivalent to 2,700 milliliters. Therefore, the mass of 2.7 L of water is approximately 2,700 grams, or 2.7 kilograms.
