An empty LPG cylinder weights \( 14.8 \, \text{kg} \). When full, it weights \( 29.0 \, \text{kg} \) and shows a pressure of \( 3.47 \, \text{atm} \). In the course of use at ambient temperature, the mass of the cylinder is reduced to \( 23.0 \, \text{kg} \). The final pressure inside the cylinder is ____ \( \text{atm} \). (Assume LPG to be an ideal gas)
