19. You have two small sculptures made of copper and gold. The first sculpture has 5% gold while the second one has 10% gold. The first sculpture has twice the mass of the second one. You melt both, extract the gold and you make a ring of pure gold that is 10 g. What is the mass of the lighter sculpture?

The law of atmospheres states that the number density of molecules in the atmosphere depends on height y above sea level according to nV(y)=n0en0gy/kaT where n0 is the number density at sea level (where y = 0). The average height of a molecule in the Earths atmosphere is given by yavg=0ynV(y)dy0nV(y)dy=0yen0gy/kaTdy0en0gy/kaTdy (a) Prove that this average height is equal to kBT/m0g. (b) Evaluate the average height, assuming the temperature is 10.0C and the molecular mass is 28.9 u, both uniform throughout the atmosphere.
