Water Mass Formula:
| From: | To: |
The mass of water is calculated using the formula: MW = D × V, where MW is the mass of water in grams, D is the density of water in g/mL, and V is the volume of water in mL. For pure water at standard conditions, the density is approximately 1 g/mL.
The calculator uses the water mass formula:
Where:
Explanation: The formula multiplies the density of water by its volume to determine the mass. For pure water at 4°C, density is exactly 1 g/mL, making the calculation straightforward.
Details: Calculating the mass of water is essential in chemistry, biology, cooking, and various industrial processes where precise measurements are required for experiments, formulations, or recipes.
Tips: Enter the density of water in g/mL (default is 1 g/mL for pure water) and the volume in mL. All values must be positive numbers.
Q1: Why is the density of water typically 1 g/mL?
A: At standard temperature and pressure (4°C and 1 atm), pure water has a density of exactly 1 g/mL, which serves as a reference point for many calculations.
Q2: Does water density change with temperature?
A: Yes, water density varies with temperature. It's highest at 4°C (1 g/mL) and decreases as temperature increases or decreases from this point.
Q3: How does salinity affect water density?
A: Saltwater has a higher density than pure water due to dissolved salts. Seawater typically has a density of about 1.025 g/mL.
Q4: Can this calculator be used for other liquids?
A: Yes, the formula MW = D × V works for any liquid, but you must use the correct density value for that specific liquid.
Q5: How precise is this calculation?
A: The precision depends on the accuracy of your density and volume measurements. For most applications, using 1 g/mL for pure water provides sufficient accuracy.
