Question
initial temp : 19.06 C
Trial 1: (0.5 M)(0.200 mL)= 0.1
-56000 J/mol = (-200g)(4.18 J/g C)(Tf- 19.06 C)
66.986= Tf - 19.06
66.986 + 19.06 = Tf
86.04 C = Tf
my predicted final temp: 86.04
experimental final temp: 24.53
Compare your predicted change in temperature to the experimental change in temperature. What is the percent error?
What could be the reasons for your error?
Expert Solution
Step 1
Percentage error
= (86.04 - 24.53) *100/ 24.53
=250.75%
