The mass of the whole doesn't change, it's simply the sum of the mass of the solute and the mass of the solvent.

Difference between organic and inorganic solvents?
Like dissolves like. Polar solvents dissolve polar solutes best, and non-polar solvents dissolve non-polar solutes best. Water is a polar molecule, and it therefore dissolves other polar molecules or ionic compounds. Organic solvents are generally not as polar as water or completely non-polar, so things like hydrocarbons, high molar mass alcohols and molecular compounds dissolve best in them.Also, water can hydrogen bond extremely well, which results in some of its unique properties, such as it's high boiling point (especially for it molar mass) and it's high surface tension. Typically organic solvents have much lower boiling points and a lower surface tension.It's also worth mentioning that water is completely non-toxic and environmentally benign, whereas most organic solvents are fairly toxic, especially if ingested, and many are carcinogenic.
What can be added or taken away from an atom to change the atomic mass?
Neutrons can be removed or added to change the atomic mass of an atom; a atom with the same amount of protons but different amounts of neutrons are called isotopes.(Taking or removing protons would change the type of atom and electrons do not have sufficient mass to change the atomic mass.)
How does the atomic mass change when a proton is added to its nucleus?
Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.
What must be added or taken away for a change in the state of matter to occur?
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
Does boiling an egg increase its mass?
as long as the shell doesn't crack no. Adding heat to something wont change its mass unless something is added or taken away from the egg
When does volume change?
when more mass is added

What about matter can change and what does not change according to law?
mass cannot change quanity if it is not added or removed
When fuel is burnt does its mass change?
Yes the Mass does change because the Material is oxidised. So if something is added to the material therefore the mass increases

What about matter can change and what does not change according to the law of conservation of matter?
mass cannot change quanity if it is not added or removed
Does a change in the mass affect the density of the object?
Adding mass may increase or decrease the density if the substance added is different. Merely changing the mass will not affect the density.
Why doesnt the mass number change when electrons are added or removed?
The mass of an electron is very small, almost negligible, compared to that of a proton or neutron.
Why doesn't the mass of a beaker full of ice change as it melts?
Because it is a physical change only. Nothing, except heat, is added or removed in the process.

What can you change to keep a log at the same level if mass is added to the log?
Move the log so that it is resting on a solid surface!
