Asked by lyne
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

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.
