Question

Juan is making spaghetti and he adds 29 grams of `NaCl` to 250 grams of water. What is the boiling point of this solution?

Answer 1

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.

Answer 2

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.
