Question

QUESTIONS 1. a. Compare your own group's value with the known value (see Section 9.6 in McMurry, Fay & Robinson, 7th Ed.) of AH (expressed in joules per mole of water). b. Compare the class average value to the known value (see Section 9.6 in Mc- Murry, Fay & Robinson, 7th Ed.) of AH (expressed in joules per mole of water). c. Specify three potential experimental errors that would contribute to any discrepancies observed.

Answer 1

1.708103 1. a. now I am considering the group value o atidus (s/ord) is lg joules / moler & the known value of silfusion = 6:01 kJ/ not of water on Comparing Group !! value with known value we will have a elld of / 6ool - 1.78 x 100 = 70.382% b now taking areage class value of Attention of water it 4.9978103 Indes & Compare there with known value 6.01 ks/mol. on Compaling these two values we will have a curg ( 601_4.997)x100 = 16.805./. 1 6ol c. experiment encall could be heat could have been lost during transfer from the ice bin to the Callimeter. Also the collimedel is nota perfect insulater, thermometer also can change the specific heat Capacity value.
