When 50.0 g of 0.200 m nacl(aq) at 24.1 °c is added to 100.0 g of 0.100 m agno3(aq) at 24.1 °c in a calorimeter, the temperature increases to 25.2 °c as agcl(s) forms. assuming the specific heat of the solution and products is 4.20 j/g °c, calculate the approximate amount of heat in joules produced.
