A cylinder is filled with 10.0L of gas and a piston is put into it. The initial pressure of the gas is measured to be 126.kPa. The piston is now pushed down, compressing the gas, until the gas has a final volume of 3.30L. Calculate the final pressure of the gas. Be sure your answer has the correct number of significant digits.
