One of the ideas to fix the kg using constants of nature, was to "Count atoms". A near perfect sphere of silicon was made weighing exactly 1.0 kg. We make the assumption here that the material is 100% pure 28Si. Question: Calculate how many atoms there are in a 1.0 kg 28Si sphere. Use the Avogadro Constant ( 6.022140763 * 1028 mol), the atomic mass as exactly 28 u and round off your final answer to two significant figures.

In a vacuum chamber designed for surface-science experiments, the pressure of residual gas is kept as low as possible so that surfaces can be kept clean. The coverage of a surface by a single monolayer requires about 10 19 atoms per m². What pressure would be needed to deposit less than one monolayer per hour from residual gas? You may assume that if a molecule hits the surface, it sticks.
