What is the empirical formula of the compound whose molecular formula is p4o10

The empirical formula of P4O10 is P2O5 . This is arrived at by dividing both subscripts by their highest common factor 2.

Explanation:

Empirical Formula of a compound is the lowest whole number ratio between the compound elements it is sometimes different from the standard formula of the compound).

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
