they have nonpolar structure.
they are held together by hydrogen bonds.

They are held together by hydrogen bonds.

Explanation:

H2O has very strong intermolecular forces known as hydrogen bonds because the hydrogen is bonded to oxygen, a highly electronegative element

Answer from: lauren21bunch

Option (b) is the correct answer.

Explanation:

When a hydrogen atom is bonded to an electronegative atom then bonding between the combining atoms is known as hydrogen bonding.

For example, in a water molecule due to difference in electronegativity of oxygen and hydrogen atoms there will be development of partial negative charge on oxygen atom and partial positive charge on hydrogen atom.

As a result, the water molecule will become polar in nature. And, due to opposite charges on both hydrogen and oxygen atoms there will be strong bonds between the water molecules.

Hence, we can conclude that strong bonds exist between water molecules because they are held together by hydrogen bonds.

The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance.
