Question

what is the empirical formula for \i\? input the subscript values according to the format. format: input the subscripts in order as a single number starting from left to right for each element, including a 1 value as appropriate. for example, for a formula of c₂h₃o₂br₁ or c₂h₃o₂br, the input is 2321 a. c₄h₁₄ b. c₅h₁₅o₅ c. c₇h₂₈o₁₄ d. c₃h₁₂o₆ e. c₃h₆o₃ f. c₂h₆o₂ g. fe₂(so₄)₃ h. ba₃(po₄)₂ i. fe₂(so₃)₃ j. ba₃(po₃)₂ k. n₃o₁₂ l. c₇h₂₈o₁₄

Explanation:

Step1: Find the ratio of elements in $Fe_2(SO_3)_3$

The compound $Fe_2(SO_3)_3$ has 2 iron (Fe) atoms, 3 sulfur (S) atoms and 9 oxygen (O) atoms.

Step2: Determine the empirical - formula sub - scripts

The empirical formula shows the simplest whole - number ratio of atoms in a compound. For $Fe_2(SO_3)_3$, the ratio of Fe : S : O is 2:3:9.
