If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

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.
