The mass of a water sample can be determined by counting the total number of water molecules (H2O) and summing up their individual masses. Freezing does not change the number of water molecules and can not change the mass only the arrangement of the molecules, from a liquid to a jumble of chained molecules that take up more room, are less dense and float. Remember that a given mass of water is a fixed number of water molecules and although the sample may weigh less on the moon than on earth, the mass is constant anywhere in the universe and may even be weightless in a space station circling the earth.

No - Mass is a property of a physical object that quantifies the amount of matter and energy it is equivalent to. Unlike weight, the mass of something at rest stays the same regardless of location. Mass is a central concept of classical mechanics and related subjects, and there are several forms of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.

mass of anything does not change no matter what it is subjected to. In this case mass of water remains, however volume and density changed.

no, only the volume changes. when water turns into ice it has a crystalline structure which takes up more room than when it is water and free moving.

mass stays the same
change in volume, hence change in density.
also gains a crystal structue

When it freezes it expands. If you fill a gallon jug, it expands. When you let it melt it is the same amount of water.

no,density changes when it become ice.
density=mass/volum.

no mass remains the same as we always take mco as a formula in calorimetry.
