You dissolve a 1.28-g sample of nacl in a total volume of 125.0 ml of solution. your lab partner has 1.50 m aqueous nacl and wants to make a solution with the same concentration and volume as yours. how much of the solution does your lab partner need to use?

The 14.59 mL of solution is needed by our lab partner.

Explanation:

Mass of the NaCl = 1.28 g

Moles of NaCL =

V = Volume of the solution in Liters.

= 125.0 mL = 0.1250 L

Molarity of our solution =

Molarity of the lab partner's solution =

Volume of the lab partner's solution = = ?

The 14.59 mL of solution is needed by our lab partner.

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.
