Question
In this experiment you will place a sample of your salt in water in a constant pressure calorimeter with a heat capacity of 29.4 J/℃. You will determine the enthalpy change for the dissociation of your salt, delta Hdiss or rxn. A sample of 4.368 grams of the salt SrCl2 was placed in 35.5 g water, the initial temperature was 20.00℃ and the final temperature was 27.086365℃. What is the total mass of the solution in sig figs? mass = 4.368 g + 35.5 g = 39.868 g
a. 39.8 g
b. 40 g
c. 39 g
d. 39.868 g
e. 4.0 x 10^1 g
f. 39.87 g
g. 39.86 g
h. 39.9 g
i. none of these
