# Question: A cube 10 0 cm on each edge contains air with equivalent molar

A cube 10.0 cm on each edge contains air (with equivalent molar mass 28.9 g/mol) at atmospheric pressure and temperature 300 K. Find
(a) The mass of the gas, (b) its weight, and
(c) The force it exerts on each face of the cube.
(d) Comment on the physical reason why such a small sample can exert such a great force.
