You Like Boiled Eggs for Breakfast, but They Take Too

question 33

Multiple Choice

You like boiled eggs for breakfast, but they take too long to cook, and you are always late to your early morning class. Lucky you! You have learned that adding table salt, NaCl (58.4 g/mol, 2.16 g/cm³) , to water (K_b = 0.52^oC/m) increases the temperature at which it boils. You figure that you can cook eggs faster at a higher temperature in boiling salty water! What increase in the boiling point do you expect if you add 1 tablespoon (1 tbsp = 14.8 cm³) of salt to one 8-oz cup of water (237 mL) ?

• A) 1.0°C
• B) 2.4°C
• C) 28°C
