the ideal gas constant D:
To determine the volume of a gas using the formula for calculating gas volume, you would need to know the amount of gas in moles (n) and the gas constant (R), and the temperature (T) and pressure (P) of the gas. The formula for calculating gas volume is V (nRT) / P, where V is the volume of the gas. By plugging in the values for n, R, T, and P into the formula, you can calculate the volume of the gas.
PV = NRT where : P is the pressure of the system V is the volume of the system N is the number of moles of the gas R is the gas constant (8.314jk-1mol-1) T is the temperature of the system
