En un recipiente de 3L tenemos un gas que ejerce una presión a 3atm cuando su temperatura es de 6°c¿cual será su volumen , si la presión es de 1.25atm y no varia la temperatura

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
