Experiment Method changes

I did some research and I've found that for every 1 litre of water, the boiling point increases by 1.024 degrees Celsius for every 58.43 grams of sodium chloride (table salt). In this case, it means that for me to even see that there is a change occurring in the experiment, there is no way that 5 gram intervals is going to be enough. Therefore, what I am going to do is say that I will add salt in 20g or more intervals, 5 times which according to this formula should mean that for 100g of sodium chloride added, the boiling point of the water should increase by approximately 1.75 degrees Celsius.
I am reconsidering the quantities that I am going to add at the moment so that the experiment will work properly. I'm going to use the same method and do the experiment sometime in the next few days.
First, I want to find out- cause ok, its reallllyyyyyy complicated but very basically the boiling point elevation describes how the boiling point of a liquid (solvent) in this case, it's water will be higher when another compound is added to it. That means that a solution has a higher boiling point than a pure solvent but this depends on the volatility of a solute so this happens when a NON-VOLATILE SOLUTE (the salt) is added to a pure solvent (water)- and i looked up what that meant and it means "The state of being volatile The state of having a low boiling point and evaporating readily"- thankyou wiktionary :)
SO to rephrase that, when a non-volatile solute is added to a pure solvent, the boiling point of the the solution after the other compound is added to it, will elevate.
This is pretty much the simplest way I can explain it right now...but that's what the experiment is for SO i will do more research on this andddd i feel smarter already :D
