Hydrolamine ,NH2OH , is a reducing agent found in some film developing solutions. How many hydrogen atoms are in 1.80moles of hy
kolezko [41]

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

How many moles of carbon are in 6.0 moles of quinine
damaskus [11]
The molecular formula of quinine is C20H<span>24N2</span>O<span>2. For every 1 mole of quinine molecule, there are 20 moles of carbon. Simply multiplying 6.0 moles by 20, we get, 120 moles.
Therefore, there are 120 moles of carbon in 6.0 moles of quinine.</span>
