Transcribed Image Text:**Question 5**
A 10.1 g sample of NaOH is dissolved in 250.0 g of water in a coffee-cup calorimeter. The temperature increases from 23.0 °C to _____ °C. The specific heat of liquid water is 4.18 J/g·K and ΔH for the dissolution of sodium hydroxide in water is 44.4 kJ/mol.
A) 33.3
B) 40.2
C) 33.7
D) 35.2
E) 24.0
This question involves a calorimetry experiment where sodium hydroxide (NaOH) is dissolved in water, causing a temperature change in the solution. The specific heat capacity of the water is provided, as well as the enthalpy change for the dissolution process. The task is to determine the final temperature after the dissolution has occurred. The multiple-choice options suggest possible final temperatures, and the calculations would involve using calorimetry and stoichiometry principles.
