Dear Student,
Assuming the gas to be ideal and converting the temperature to kelvin as Temperature in equation should be in kelvin.then applying the ideal gas equation at initial and final condition gives us the result.I have done the question below .
If something is not clear or need further clarification please
feel free to comment here without hesitation.

A gas was initially held at -50.00 °C at a pressure of 25 atm. After heating the gas to 30.00 °C, the pressure decreased to 15 atm, and the volume of gas was found to be 25 L. What was the initial volume of the gas? • Use --273.15 °C for absolute zero. • Report your answer with two significant figures.
