The enthalpy of solution for LiBr is - 48.8 kJ/mol. Suppose 5.0 g of LiBr is dissolved in 50.0 g of water. The initial temperature of the water is 20.0 °C. What is the final temperature of the water? The specific heat of water is 4.184
J/(9*°C).
Select one:
a. 6.6 °C
b. 33.4 °C
c. 32.2 °C
d. 7.8 °C

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
