Answer both questions please:

1) (1.2 points) For N gas molecules of mass m in a cube of side length L, derive an expression for the force exerted by the gas on one wall of the cube by a single molecule. Indicate the final result by drawing a box around it.

 

2) (1.6 points) Molecules of a gaseous ether at $T=250C have a most probable velocity of = 273.8 m/s. Draw three possible Lewis diagrams for the ether.

(R = 8.314 J /mole K) (Atomic masses in g/ mole: C = 12.0, H = 1.0, O = 16.0, N = 14.0)
