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

Aug 22, 2016

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.
