How to convert it to standard cubic?

How to convert the volume of a gas at a certain pressure and temperature to standard cubic units? Thank you:handshake
P1*V1 / T1 = P2*V2 / T2. P represents pressure, V represents volume, and T represents temperature. Under different pressure and temperature conditions, a gas of the same mass has different volumes. By using the standard pressure for P2 and the standard temperature for T2, it is possible to determine the standard volume. Haha; this seems to be something covered in high school physics.

What are the values for standard pressure in P2 and standard temperature in T2? Please share.
If it is within the range of an ideal gas, then the value of Vs can be calculated using the ideal gas equation: Vs = PVTs / (T*Ps). Here, Ps, Vs, and Ts represent the pressure (1 atm), volume, and temperature under standard conditions, while P, V, and T represent the pressure, volume, and temperature under actual conditions. If it is not an ideal gas, a compressibility factor must also be added to the equation above.
Uh, of course it refers to pressure and temperature under standard conditions……
The standard volume of a gas refers to the volume of the gas at a pressure of 100 kPa and a temperature of 0 degrees Celsius. If the pressure of the gas is not very high, it can be calculated using the ideal gas law equation PV=nRT; the volume is expressed in cubic meters, and the result obtained is the standard volume of the gas.

Temperature is in Kelvin; 0 degrees Celsius = 273.15 K
The so-called standard volume refers to the volume under standard conditions; the original poster can convert the volume at any other condition using the formula PV/T = C
Using PV=nRT: P_workV_work=nRT_work, P_standardV_standard=nRT_standard. Since nR is the same, T=273+temperature
