How to calculate initial pressure of a system

Answers

GPT 3.5
To calculate the initial pressure of a system, you can use the ideal gas law equation:

PV = nRT

Where:
P = pressure
V = volume
n = number of moles of gas
R = ideal gas constant (0.0821 L.atm/mol.K)
T = temperature in Kelvin

If you know the volume, number of moles, and temperature of the gas in the system, you can rearrange the ideal gas law equation to solve for pressure:

P = (nRT) / V

Simply plug in the values for n, R, T, and V into the equation and solve for P to find the initial pressure of the system.
