Volume of Gas Formula:
From: | To: |
Definition: This calculator determines the volume occupied by a gas based on its molar mass, most probable velocity of molecules, and the pressure exerted by the gas.
Purpose: It helps in understanding gas behavior and calculating gas volumes under specific conditions in physics and chemistry applications.
The calculator uses the formula:
Where:
Explanation: The formula relates the kinetic energy of gas molecules (represented by their most probable velocity) to the pressure and volume of the gas.
Details: Accurate gas volume calculations are essential for designing chemical reactors, understanding gas behavior in different conditions, and various industrial applications.
Tips: Enter the molar mass in kg/mol, most probable velocity in m/s, and gas pressure in Pascals. All values must be positive numbers.
Q1: What is most probable velocity?
A: It's the speed at which the largest number of gas molecules are moving at a given temperature.
Q2: How do I find molar mass of a gas?
A: Molar mass can be calculated by summing atomic masses of all atoms in the molecule or found in chemical reference tables.
Q3: What units should I use for pressure?
A: The calculator uses Pascals (Pa). 1 atm = 101325 Pa, 1 bar = 100000 Pa.
Q4: Does this work for ideal gases only?
A: The formula is derived from kinetic theory of ideal gases, but can approximate real gas behavior under many conditions.
Q5: How does temperature affect the result?
A: Temperature affects the most probable velocity (Cmp), which is included in the calculation.
