Here's how to figure out the number of hydrogen atoms in 2 molecules of hydroxylamine:

1. The Formula:

* Hydroxylamine has the chemical formula NH₂OH.

2. Hydrogen Atoms per Molecule:

* There are a total of 4 hydrogen atoms in each hydroxylamine molecule (2 from the NH₂ and 1 from the OH).

3. Total Hydrogen Atoms:

* Since we have 2 molecules of hydroxylamine, we multiply the number of hydrogen atoms per molecule by 2: 4 hydrogen atoms/molecule * 2 molecules = 8 hydrogen atoms.

Therefore, there are 8 hydrogen atoms in 2 molecules of hydroxylamine.
