CH20. The molecular mass of water is 18 u. The mass of a teaspoon of water is 4.9×10−3 kg. If one teaspoon of water were spread evenly over the surface of the Earth, what would be the surface number density, that is, the number of water molecules per square meter? (Assume the Earth is a smooth sphere with radius 6.4×106 m.)
