Water Volume Calculation:
| From: | To: |
The mol to liter conversion for water is based on the molar concentration of pure water. At standard conditions, the molarity of water is approximately 55.5 mol/L, meaning 1 liter of water contains about 55.5 moles of water molecules.
The calculator uses the simple formula:
Where:
Explanation: This formula converts the amount of water substance (in moles) to the corresponding volume (in liters) for pure water at standard conditions.
Details: Accurate conversion between moles and liters is essential in chemistry for preparing solutions, calculating concentrations, and understanding the relationship between amount of substance and volume in aqueous systems.
Tips: Enter the number of moles of water. The value must be a positive number. The calculator will compute the corresponding volume in liters.
Q1: Why is the conversion factor 55.5?
A: This comes from the density of water (1 g/mL) and the molar mass of water (18.015 g/mol), giving approximately 55.5 mol/L at standard conditions.
Q2: Does this conversion work for all temperatures?
A: The 55.5 value is approximate and based on standard conditions (25°C). Water density changes slightly with temperature, affecting the exact conversion.
Q3: Can this be used for solutions other than pure water?
A: No, this conversion is specific to pure water. For aqueous solutions, additional factors like solute concentration must be considered.
Q4: What are typical mole values used in this calculation?
A: Typical values range from millimoles to hundreds of moles, depending on the scale of the chemical process or experiment.
Q5: How precise is this conversion?
A: The conversion is sufficiently precise for most educational and general laboratory purposes, though for highly precise work, temperature-specific density values should be used.
