Answer:
Hydrogen bond is a <em>special type of dipole-dipole interaction between the hydrogen atom in a polar bond, such as N-H, O-H, or F-H, and electronegative O,N or F atom</em>. The interaction is written:
A-B . . . B or A-H . . . .A
A and B represent O,N or F; A-H is one molecule or part of a molecule and B is a part of another molecule, and the dotted represents the hydrogen bond. So, hydrogen bond is a type of intermolecular forces (attractive forces between molecules, <u>NOT</u> between atoms of the same molecule), and only a few elements can participate on hydrogen bond formation.
<em>Note: dipole-dipole interactions are forces between polar molecules, that is, between molecules that possess dipole moments. </em>

Explanation:
Hello there!
In this case, for this units conversion problem, it turns out necessary to write the equivalence statement for liters and quarts as follows:
1 qt = 0.946353 L
Thus, the conversion set up turns out to be:
![4.22qt*\frac{0.946353 L}{1qt} \\\\=3.99L](https://tex.z-dn.net/?f=4.22qt%2A%5Cfrac%7B0.946353%20L%7D%7B1qt%7D%20%5C%5C%5C%5C%3D3.99L)
Next, we convert to microliters as follows:
![3.99L*\frac{1\mu L}{10^{-6}L}\\\\=3.99x10^6 \mu L](https://tex.z-dn.net/?f=3.99L%2A%5Cfrac%7B1%5Cmu%20L%7D%7B10%5E%7B-6%7DL%7D%5C%5C%5C%5C%3D3.99x10%5E6%20%5Cmu%20L)

2.5X20=50g
50g should be the right answer
Mass=volumeXdenisty.
C chemical really get rid of them
