Answer:
number of hydrogen atom in 1.8 mole of NH2OH = 
Explanation:
percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule
=
\times 100
= 9.09 percentage
therefore number of moles in 1.8 moles of hydroxy amine = 
= .16 moles of hydrogen
number of hydrogen atom = (number of moles )×(avagadro number)
=
atoms of hydrogen
I believe the correct answer is B
