Question

Hydrolamine ,NH2OH , is a reducing agent found in some film developing solutions. How many hydrogen atoms are in 1.80moles of hydroxylamine?

Answer 1

Answer:

number of hydrogen atom in 1.8 mole of NH2OH = $9.8\times 10^{22}$

Explanation:

percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule

                                                             =$\frac{3\times 1}{14+3+16}$\times 100

                                                             = 9.09 percentage

therefore number of moles in 1.8 moles of hydroxy amine = $\frac{9.09}{100}\times 1.8$

                                                                = .16 moles of hydrogen

number of hydrogen atom = (number of moles )×(avagadro number)

                                              = $9.8\times 10^{22}$ atoms of hydrogen
