How many miles of silver nitrate do 2.888 x 10^15 formula units equal?

4.8x10^-9 mol

Explanation:

1mole of Silver nitrate contains 6.02x10^23 molecules

Therefore, Xmol of silver nitrate will contain 2.888x10^15 molecules i.e Xmol of silver = 2.888x10^15/6.02x10^23 = 4.8x10^-9 mol

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.
