Need more data to answer. Are you talking about the mass of an object, neither air nor water, being the same when in the air or in the water? Yes. Are you talking about the total mass of all the air on earth compared to the total mass of all the water on earth? Definitely not.
this is because the amount of solute in the solution will have the same number of moles as that of the solid.
mass of solid matter without water.
mass and something are same
After water has been boiled, its mass will stay the same.
There is a thing called heavy water. It is pure water that has a deuterium in it known as D20 instead of H20. It is pure but does not have the same mass.
A solid and liquid have the same mass if the amount is the same.

The water turns from a liquid to a solid
Yes, a solid would have the same mass on the moon as it would on earth. An object's mass is independent of the force of gravity, so its mass would remain the same even in the absence of gravity (e.g. on a spaceship). What would change is the weight, which is measured with mass in proportion to gravity.
The molar mass of water (H2O) is 18. Ice is water in it's solid state.
they are both water
After water has been boiled, its mass will stay the same.
Nothing, if it is the same amount of material in all three phases.If however it is the same volume and pressure then solid and liquid phases will have about equal mass but the gas phase will have much less mass.
The mass remains the same.
