Twenty-five milliliters of liquid nitrogen (density = 0.807 { g/mL}) is poured into a cylindrical container with a radius of 10.1{ cm} and a length of 18.3{ cm} . The container initially contains only air at a pressure of 760.0 {mmHg} (atmospheric pressure) and a temperature of 306{ K} .

If the liquid nitrogen completely vaporizes, what is the total force (in {lb}) on the interior of the container at 306{ K} ?

You must show you have attempted the question, this is a Forum Rule.

So i start with getting the volume and area of the cylinder.Then i find P for Nitrogen using P=(nRT)/V
add the pressure of N2 to that of the air in container and to get total force i multiply pressure in lb/sqinch by area in sq inch to get lb total pressure. Is my roadmap correct or am i missing something?

Logic behind looks OK.
