Write formulas for the compounds that form from In and each of the following polyatomic ion: NO−3, SO2−4, PO3−4.
(Assume In charge is 3+.)
InNo9, InSO6, AND InP4 is wrong
(Assume In charge is 3+.)
InNo9, InSO6, AND InP4 is wrong

NO-3 ? , SO2-4 ?, PO3 -4
Where did you get these strange charges for the ions?
eg PO3 normally -3
ASSUMING your strange valences:
In +3
NO -3
then to be neutral
InNO
In+3 * 4 = +12
SO2-4 * 3 = -12
so
In4(SO2)3
similarly
In4 (PO3)4
But I suspect you have the original statement messed up

I'm sure you mean [NO3]^-, [SO4]^2- etc.
Then In(NO3)3, In2(SO4)3, etc.
If we could write subscripts very well on this forum the nitrate would be [NO<sub>3</sub>]<sup>-</sup>
