Which is a saturated solution? 1) 52 g KCl in 100 g water at 80ºC
2) 40 g NH4Cl in 100 g water at 50ºC
3) 2 g SO2 in 100 g water at 10ºC
4) 120 g KI in 100 g water at 20ºC

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
