Matching Formula Units with the Number of Oxygen Atoms

To determine the correct matching between the formula units and the number of oxygen atoms, let's analyze each option:

A. Ca(HSO4)2 - This compound contains two sulfate ions (SO4^2-) and two hydrogen ions (H+). - Each sulfate ion contains four oxygen atoms, so the total number of oxygen atoms in Ca(HSO4)2 is 2 * 4 = 8.

B. Mg(HSO3)2 - This compound contains two bisulfite ions (HSO3-) and two hydrogen ions (H+). - Each bisulfite ion contains three oxygen atoms, so the total number of oxygen atoms in Mg(HSO3)2 is 2 * 3 = 6.

C. (CaOH)2SO3 - This compound contains two hydroxide ions (OH-) and one sulfite ion (SO3^2-). - Each hydroxide ion contains one oxygen atom, so the total number of oxygen atoms from the hydroxide ions is 2 * 1 = 2. - The sulfite ion contains three oxygen atoms. - Therefore, the total number of oxygen atoms in (CaOH)2SO3 is 2 + 3 = 5.

D. KPOAIF.SC - The given formula "KPOAIF.SC" seems to be incomplete or incorrect. It does not correspond to any known compound or element.

Based on the analysis, we can conclude that: - Option A (Ca(HSO4)2) corresponds to 8 oxygen atoms. - Option B (Mg(HSO3)2) corresponds to 6 oxygen atoms. - Option C ((CaOH)2SO3) corresponds to 5 oxygen atoms. - Option D (KPOAIF.SC) is not a valid formula.
