Calculate the energy needed to melt 3.6 g of ice at 0oC. The molar heat of fusion for ice at 0oC is 6.02 kJ/mol.

Amount of liquid measured in l or lm

Joan writes four numbers on the board in standard form, and then she writes their scientific notation

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.
