6small glass beads are found to weigh 9.34 g. the beads are placed in a graduated cylinder filled with ethyl alcohol (density 0.78 g/ml). the reading of the liquid in the cylinder before the beads were added is 21.5 ml. after the beads sink to the bottom of the alcohol the reading is 24.5 ml. calculate the density of the beads. be sure to record your answer with the correct number of significant figures. did it matter than alcohol rather than water is used in this experiment? why or why not? does it matter that this experiment was done with a collection of glass beads rather than a single solid object? why or why not?

po-215 i got it right on the quiz

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.
