how many atoms of tungsten are in 504.56 g of tungsten(IV)acetate.

i attempted this problem but ended up with atoms of tungsten(IV) acetate in tungsten(IV) acetate instead of atoms of just tungsten in tungsten(IV) acetate.

please help
thanks

  • chemistry - ,

    WRite the formula:

    W(acetate)4
    so there are the same number of atoms of tungsten as is molecules of tungsten acetate.
    moles=mass/molmass
    molecules tungsten acetate=moles*avagnumber
    atomstungsten=moles*avanumger
    acetateions=moles*4*avanumber.
