Binary mixtures of NiO and Mo were prepared containing 20,50,and 80 weight percent of NiO.

20g of Al (internal standard) were added to 70 g of these mixtures and to 70 g of an unknown mixture of NiO and Mo. The intensity of suitable reflections were recorded.

NiO(wt%)   Mo(wt%)  I(NiO)   I (Mo)   I (Al)   I(NiO)/I(Al)   I(Mo/IAl)

20                  80          73        639      246

50                  50         196       423      261

80                  20         508        271     423

  Unknown                   227       364     263

Calculate I(NiO)/I(Al) and I(Mo)/I(Al) and plot vs % NiO and % Mo respectively

Determine composition of unknown : wt % NiO and wt % Mo in unknown mixture
