What volume in ml of a 0.763 m solution of bai2 would be required if you wanted 0.0131 moles of solute? ml (picture attached)

The right answer is V = 17.2 mL

Explanation:

No. of moles = C * V

where,

C is the concentration in morality and

V is the volume in liter

so you can calculate the volume using:

V = (No. of moles / C) = (0.0131 mol / 0.763 mol/L)

V = 0.0172 L

 V = 0.0172 L * (1000 mL / 1 L)

  V = 17.2 mL

So, the right answer is V = 17.2 mL

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.

your answer is c) plasma
