Could someone please tell me what I am doing wrong? The question is: "5,00 liters of a gas at a temperature of 25,0 degrees Celcius and 0,500 atmospheric pressure is compressed to a volume of 1,00 liters and the temperature is not changed. What is the new pressure in that situation?"
I have attached my answer. The correct answer is 2,50. 10^5 𝑃a.
