How many lone pairs does the hydrogen molecule contain h2?

None

Explanation:

Lone pairs of electrons are a set of 2 electrons pair which are not involved in bonding but are present in the outermost shell of the electron.

To accurately get them, we can primarily use the Lewis dot formula. After drawing our bonds, we can still some pairs of electrons which are nonbonding but are present.

Hydrogen atom has one electron. To form the hydrogen gas molecule, each hydrogen atom donates an electron each for sharing via covalent bonding, hence both electrons are used for bonding and we do not have any extra electrons.
