    hi

    Student

    hi.

    Tutor

    well u can think like this

    Tutor

    one atom weight would be how much

    Tutor

    of Fe

    Tutor

    see atomic mass of Fe in PT

    Student

    55.91 ish

    Tutor

    ok

    Student

    more like 55.85

    Tutor

    then u know one atom will ne 55.85 amu ( atomic mass unit )

    Student

    okay

    Tutor

    and u know the weight of one amu

    Tutor

    so one atom weight will be 55.91x 1.6606E-24 gm

    Tutor

    so 53723 atom

    Tutor

    will be

    Tutor

    how much

    Tutor

    ?

    Tutor

    53723 x 55.91x 1.6606E-24 gm
