A container of LPG 55 Cu Meter volume capacity is having LPG vapour only at 6 Bar pressure. How much LPG in Kg would have been used to reach at this stage?

To determine the amount of LPG used to reach 6 Bar pressure in a 55 Cu Meter container, you need to know the temperature of the LPG as pressure and volume alone are not sufficient. The amount of LPG in kg can be calculated using the ideal gas law equation PV = nRT, where P is pressure, V is volume, n is the amount of substance in moles, R is the ideal gas constant, and T is the temperature in Kelvin.
