What are the final concentrations of all the ions when following are mixed?
`50 mL of 0.12M Fe(NO_(3))_(3), 100 mL of 0.10M FeCl_(3)` and `100mL of 0.26M Mg(NO_(3))_(2)`

A

`[Fe^(3+)] = 0.064 M, [NO_3^(-)]=0.28M, [Fe^(3+)]=0.12,[Mg^(2+)]=0.04M`

B

`[Fe^(3+)] = 0.064 M, [NO_3^(-)]=0.28M, [Fe^(3+)]=0.12,[Mg^(2+)]=0.104M`

C

`[Fe^(3+)] = 0.04 M, [NO_3^(-)]=0.28M, [Fe^(3+)]=0.12,[Mg^(2+)]=0.104M`

D

`[Fe^(3+)] = 0.064 M, [NO_3^(-)]=0.8M, [Fe^(3+)] = 0.12 M, [Mg^(2+)]=0.104M`
