In my Applied Math class I was asked the following question and told the answer will be in atm with a decimal number rounded to the nearest hundredth. But I don't know how to reach the conclusion and what formula to use, if there are 8.8 liters of gas in a piston at a pressure of 1.75 atmospheres and The temperature remains constant, and the gas is compressed to a volume of 6.2 liters. What is the new pressure, in atmospheres, inside the piston, please assist.
