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 142.kPa. The piston is now pushed down, compressing the gas, until the gas has a final volume of 3.70L. Calculate the final pressure of the gas. Round your answer to 3 significant dig

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.
