Unformatted text preview: ions in calcium acetate. Both of these conversions can be determined if we know the chemical formula of the ionic compound. Ionic compounds are neutral, so we need to add enough of each ion to make a neutral compound. This would occur with one calcium cation and two acetate anions like this: Ca +2 + 2CH 3 COO-1 → Ca(CH 3 COO) 2 Oftentimes the charge on one ion will become the subscript on the other ion when written as an ionic compound. Here is the dimensional analysis: 40g Ca(CH 3 COO) 2 │1 mol Ca(CH 3 COO) 2 │ 3 mols ions │6 x 10 23 ions │160g Ca(CH 3 COO) 2 │1 mol Ca(CH 3 COO) 2 │1 mol ions = 4.5x10 23 ions...
