Question

The folloning data was collected after running a calorimetric experiment using three salts. Table 1: AHsol Valucs of Salts Salt Lit LiNO Hsol (kJ/mol) 63.60 Tha data collected for each experiment !ち器follows. Experlment 1: 2.80 g of unknown salt added to 140. mL of water reaulted In a AT valua a-0.2C Experiment 2: 2.80 g of unknown salt added to 140. mL of water resulted in a Δτ value of-2.3°C. Experiment 3: 2.80 g of unknown salt added to 140. mL ot water resulted in a Δτ value ot 0.9°C, Calculate the value of for cach of the cxperimants. (Asue that the haat capacity of water is 4.1801 Jg.C.) Experimen! 1 un-80 Cxperiment 2 Experiment 3 to sea If your deduction makes sense when compared to tha Rased an the magnitude and sign af the qvalues calaulated, detarmine the Identity of tha salt usad in each expariment and the resulting Hsol hasad on that daductian.
