In order to find out the density of a small rock, eddie dropped the rock into a graduated cylinder fill with 52.5 ml of water. the level of the water went up to 68.1 ml. eddie then placed the rock on a triple beam balance, and its mass was 27.69 g. a. what is the volume of the rock? b. what is the density of the rock?

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
