Answer:
number of hydrogen atom in 1.8 mole of NH2OH = [tex]9.8\times 10^{22}[/tex]
Explanation:
percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule
=[tex]\frac{3\times 1}{14+3+16}[/tex]\times 100
= 9.09 percentage
therefore number of moles in 1.8 moles of hydroxy amine = [tex]\frac{9.09}{100}\times 1.8[/tex]
= .16 moles of hydrogen
number of hydrogen atom = (number of moles )×(avagadro number)
= [tex]9.8\times 10^{22}[/tex] atoms of hydrogen
