It is LESS than the mass of 2.5*cm^32.5cm3 of liquid water.

Explanation:

"Mass "=" Volume"xx"density"Mass = Volume×density

=2.5*cm^3xx0.917*g*cm^-3=2.5cm3×0.917gcm3 == ??g??g

You will note that the solid phase is less dense than the liquid phase. This is an unusual phenomenon, and of course is the reason why icebergs float, and the Titanic went south. We would expect that a liquid phase should be less dense than a solid phase; however, water, a highly peculiar (and biologically vital) solvent, does not conform to the expectation.
