Sugar is easily soluble in water and has a molar mass of 342.30 g/mol. What is the molar concentration of a 252.6 mL aqueous solution prepared with 70.3 g of sugar?

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.

you need to have a picture of the atom that way we can answer it

the answer is 2-methylbutane. i just took a quiz and i got it wrong and this is what my teacher sai the correct answer was.
