What formula and steps do i use to determine if there are 8.88.8 liters of gas in a piston at a pressure of 1.751.75 atmospheres and the temperature remains constant, and the gas is compressed to a volume of 6.26.2 liters then what is the new pressure, in atmospheres, inside the piston, and I want it to be a number rounded to the nearest hundredth, with the appropriate unit, like this, 42.53 atm.
