The question is : what will the final volume be?
I had never done this before for some reason. Perhaps laziness?
I measured 50 mL of water. I calculated that 15 g of table salt should completely dissolve in it.
The final volume is more than 50 mL. It is closer to 56 mL and that is a huge difference.
If at 50 mL (and whatever room temp), the density of water is 1.00 g/cm3,
then the density of the solution is = 1.16 g/cm3

I was tough that when you dissolve a salt into water that the volume doesn't change. The density goes up.
The salt is suppose to occupy the empty space between the water molecules.

I will try it with sugar as well.

Volume changes, density changes, there is no simple way of calculating neither - best approach is to use density tables.

Check my concentration calculator (see the signature).

I see.
How does your software balance equations so fast?
Example :
KNO3 + C12H22O11 -> N2  + CO2 + H2O + K2CO3

I wrote a program that solves it by brute force and uses multithreading and it takes a while to solve.
