Formulas of Chemistry Volume Calculator
Formula 1: Volume from Mass and Density
The formula to calculate the volume of a substance when mass and density are known is:
Volume = Mass / Density
Where:
- Volume = The space occupied by the substance, measured in liters (L), cubic meters (m³), or other appropriate units.
- Mass = The mass of the substance, typically measured in grams (g) or kilograms (kg).
- Density = The mass per unit volume of the substance, typically in grams per liter (g/L) or kilograms per cubic meter (kg/m³).
Formula 2: Volume in an Ideal Gas System
To calculate the volume of a gas under ideal conditions (using the ideal gas law), the formula is:
Volume = (n × R × T) / P
Where:
- Volume = The volume of the gas, measured in liters (L).
- n = The number of moles of gas.
- R = The ideal gas constant, which is typically 0.0821 L·atm/(mol·K).
- T = The temperature of the gas, measured in kelvins (K).
- P = The pressure of the gas, measured in atmospheres (atm).
Formula 3: Volume from Molarity and Moles
If you know the molarity and moles of solute in a solution, you can calculate the volume of the solution using this formula:
Volume = Moles / Molarity
Where:
- Volume = The volume of the solution, measured in liters (L).
- Moles = The amount of solute in moles.
- Molarity = The concentration of the solution, measured in moles per liter (mol/L).

Example of Chemistry Volume Calculator
Let’s walk through an example of each formula to see how to apply the Chemistry Volume Calculator.
Example 1: Volume from Mass and Density
You have 50 grams of a substance, and its density is 1.25 g/mL. To find the volume, use the formula:
Volume = 50 g / 1.25 g/mL
Volume = 40 mL
So, 50 grams of the substance occupies a volume of 40 milliliters.
Example 2: Volume in an Ideal Gas System
You have a sample of gas with the following parameters:
- Number of moles (n) = 2 mol
- Temperature (T) = 300 K
- Pressure (P) = 1 atm
- Ideal gas constant (R) = 0.0821 L·atm/(mol·K)
To calculate the volume of the gas:
Volume = (2 mol × 0.0821 L·atm/(mol·K) × 300 K) / 1 atm
Volume = 49.26 L
The volume of the gas is 49.26 liters under these conditions.
Example 3: Volume from Molarity and Moles
If you have 0.5 moles of a solute and the molarity of the solution is 2 mol/L, you can calculate the volume of the solution:
Volume = 0.5 mol / 2 mol/L
Volume = 0.25 L
Thus, you need 0.25 liters (or 250 milliliters) of solution for 0.5 moles of solute at 2 mol/L concentration.
Most Common FAQs
In real-world conditions, gases deviate from ideal behavior due to factors such as high pressure and low temperature. To account for these deviations, you would need to use real gas laws, like the Van der Waals equation, instead of the ideal gas law.
It’s essential to be consistent with your units. Always convert to standard units like liters (L), grams (g), or moles (mol) before performing calculations. For example, ensure your pressure is in atmospheres (atm) and temperature in kelvins (K) for gas calculations.
Yes, the calculator is versatile and can be used for liquids, solids, and gases. Just make sure you are using the correct formula for the substance in question, whether it’s for the density of a liquid, the ideal gas law, or molarity-based solutions.
