A sealed cubical container 26.0 cm on a side contains three times Avogadro's number of molecules at a temperature of 15.0°C. Find the force exerted by the gas on one of the walls of the container.

Answer 1

YOu know volume, number of moles, and temp (in K)

PV=nRT
solve for P. then, since P=F/A, multipy P by the side area (in m^2) to get force.
