Kno3(s) --> k+(aq) + no3-(aq)
this reaction was carried out in a styrofoam insulated calorimeter and the following data were recorded:
mass of solid kno3 dissolved
10.1 g
mass of aqueous solution (c = 4.18 j/gºc)
100. g
t initial
30.0ºc
t final
21.6ºc
molar mass of kno3
101 g/mol
which of the following equations correctly shows the heat of solution (kj/mol) for the dissolving of kno3?
kno3(s) + 35.1 kj --> k+(aq) + no3-(aq)
kno3(s) +3.51 kj --> k+(aq) + no3-(aq)
kno3(s) --> k+(aq) + no3-(aq) + 8.4 kj
kno3(s) --> k+(aq) + no3-(aq) + 3510 kj
