Formula Used in “Ideal Gas Pressure Calculator”
The Ideal Gas Pressure Calculator uses the Ideal Gas Law, which is represented by the formula:
P = frac{nRT}{V}
Step-by-Step Breakdown of the Formula
The formula P = nRT/V consists of several variables, each representing specific physical quantities:
- P: Pressure of the gas (expressed in atmospheres or pascals)
- n: Number of moles of gas (quantified in moles)
- R: Ideal gas constant (typically 0.0821 L·atm/(K·mol) or 8.314 J/(K·mol))
- T: Temperature of the gas (expressed in kelvins)
- V: Volume of the gas (measured in liters)
Example Calculation
To illustrate how to use the Ideal Gas Law, let’s consider a real-world example:
Scenario:
We have 2 moles of a gas contained in a volume of 10 liters at a temperature of 300 K. We want to calculate the pressure of this gas.
Inputs:
| Variable | Value |
|---|---|
| n (moles) | 2 mol |
| R (Ideal gas constant) | 0.0821 L·atm/(K·mol) |
| T (Temperature) | 300 K |
| V (Volume) | 10 L |
Calculation Steps:
- Substitute the values into the formula:
P = (2 mol) * (0.0821 L·atm/(K·mol)) * (300 K) / (10 L)
- Calculate the numerator:
2 * 0.0821 * 300 = 49.26
- Divide the result by the volume:
P = 49.26 / 10 = 4.926 atm
Output:
The pressure of the gas under the specified conditions is approximately 4.93 atm.
