Juan is making spaghetti and he adds 29 grams of #NaCl# to 250 grams of water. What is the boiling point of this solution?
2 Answers
Approximately 214.32 degrees Fahrenheit
Explanation:
The salt (NaCl) content of this water is 11.6%. 20% salty water has 216 degrees Fahrenheit boiling point.
Pure water has a boiling point of 212 degrees Fahrenheit. When you build an equation Delta t = 4 degrees F when salt has a concentration of 20%, you can calculate the boiling point of Juan's water. The answer is 214.32 degrees Fahrenheit.
100.50 degrees celcius.
Explanation:
If you dissolve 29.2 g of sodium chloride in 1 kg water, you create what is known as a "0.5 molal" solution (as opposed to 0.5 molar solution, which is 29.2 g of sodium chloride dissolved in 1 litre of solution).
The boiling point of water is raised by 0.5 degrees celcius for each 0.5 molality of the solution, so instead of boiling at 100 degrees C it would boil at 100.50 degrees C.
