Calculate the mass of 4 moles of A1,03. Then, view the video solution below. A periodic table is provided for reference.
The mass of 4 moles is

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
