Nitrogen molecules of mass 4.65 x 10\({}^{.26}\) kilograms are contained in a cube with sides that have an area of 6 x 10\({}^{.4}\) square meters. If 5.0 x 10\({}^{.23}\) molecules collide head on elastically each second with one wall at a speed of 300 meters per second, what is the pressure exerted on the wall to the nearest kilopascal?
