Chapter 5.4, Problem 4CP

Quantities of 50.0 mL of 1.00 M HCl and 50.0 mL of 1.00M NaOH are combined in a constant-pressure calorimeter. Both solutions are initially at $\text{24}\text{.4ºC}$. Calculate the final temperature of the combined solutions. (Use the data from Table 5.3. Assume that the mass of the combined solutions is 100.0 g and that the solution s specific heat is the same as that for water, $\text{4}\text{.184 J/g}\text{.ºC}\text{.)}$ The heat capacity of the calorimeter is negligibly small.

a)

$\text{31}\text{.1ºC}$

b)

$\text{29}\text{.0ºC}$

C)

$\text{44}\text{.2ºC}$

d)

$\text{91}\text{.8ºC}$

e)

$\text{35}\text{.7ºC}$
