Volume at Standard Temperature and Pressure Calculator

Formula

The formula to calculate the Volume at Standard Temperature and Pressure (STP) is:

\[ V = \frac{n \times R \times T}{P} \]

Where:

\(V\) is the volume (liters)
\(n\) is the number of moles
\(R\) is the gas constant (8.314472 J/mole*K)
\(T\) is the standard temperature (0°C = 273 K)
\(P\) is the standard pressure (1 atm = 101,325 pascals)

What are Standard Temperature and Pressure?

Standard Temperature and Pressure (STP) is a system used to simplify calculations by relating temperature and pressure to constant values. These values are 0 degrees Celsius for temperature and 1 atmosphere for pressure. These are equivalent to 273 degrees Kelvin and 101,325 pascals respectively.

Example Calculation

Let's assume the following value:

Number of Moles (n) = 2 moles

Using the formula to calculate the Volume at STP (V):

\[ V = \frac{n \times R \times T}{P} = \frac{2 \times 8.314472 \times 273}{101325} ≈ 0.045 \text{ liters} \]

The Volume at STP (V) is approximately 0.045 liters.
