If 8.00 g of ammonuim nitrate is dissolved in 1000 ml of water for use as a plant fertilizer, the water decreases in temperature form 21.00C to 20.39 C. Determine the molar heat of solution of ammonium nitrate
q = mass water x specific heat water x delta T.
q/8.00 g = heat soln J/g
Convert that to heat soln J/mole using the molar mass of NH4NO3.
