    One molecule of ammonium dichromate,{tex}\left(\mathrm{NH}_4\right)_2 \mathrm{Cr}_2 \mathrm{O}_7{/tex}

    contains 19 atoms.

    Thus, one mole of ammonium dichromate will contain 19×6.02×1023=114×1023 atoms.

    1Thank You

    Shivansh Singh 1 year, 7 months ago

    (nh4)2cr2o7 = (4+1)*2+2+7=19atoms , So that for one mole = 19*avagadro no. 19*6.023*10^23=114*10^23
