<u>Answer:</u> There are 6 hydrogen atoms present in 2 moles of hydroxylamine.
<u>Explanation:</u>
Hydroxylamine has a chemical formula of 
This compound is formed by the combination of nitrogen, hydrogen and oxygen atoms.
In 1 mole of hydroxylamine, 1 mole of nitrogen atom, 3 moles of hydrogen atom and 1 mole of oxygen atom is present.
So, in 2 moles of hydroxylamine,
moles of nitrogen atom,
moles of hydrogen atom and
moles of oxygen atom is present.
Hence, there are 6 hydrogen atoms present in 2 moles of hydroxylamine.
