Consider the nonsense units of mass: 5 zaps = 1 zoom; 1 dip = 4 pops; 18 zaps = 1 pop Find the mass of a certain brick in dips if it has a measured mass of 71.3 zooms.

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
