4.65 L of nitrogen at standard pressure is compressed into a 0.480 L container. What is the new pressure in kPa?
Semenov [28]
Assuming that nitrogen gas is ideal, we can use the equation PV = nRT to relate first conditions to the second condition. At constant temperature, pressure and volume are indirectly related as follows:
