Twenty-five milliliters of liquid nitrogen (density = 0.807 g/mL) is poured into a cylindrical container with a radius of 11.0 cm and a length of 20.0 cm. The container initially contains only air at a pressure of 760.0 mmHg (atmospheric pressure) and a temperature of 300 K. If the liquid nitrogen completely vaporizes, what is the total force (in lb) on the interior of the container at 300 K?
