The planet Zoltan is located in a solar system in the Andromeda galaxy. On Zoltan, the standard unit for the amount of substance is the wog and the standard unit for mass is the wibble. The Zoltanians, like us, chose carbon-12 to define their standard unit for the amount of substance. By definition, one wog of C-12 atoms contains 2.50 x 1021 atoms. It has a mass of exactly 12 wibbles. What is the mass, in wibbles, of 1 wog of nitrogen atoms? What is the mass, in wibbles, of 5.00 x 10-1 wogs of O2? What is the mass, in grams of 1 wog of hydrogen atoms? Expert Solution
