Question
**Question:** The percent by mass of cobalt(II) in \( \text{Co}_3(\text{PO}_4)_2 \) is ______%. **Explanation:** This question asks for the percent by mass of cobalt(II) in the compound cobalt(II) phosphate, represented as \( \text{Co}_3(\text{PO}_4)_2 \). To find this, you would: 1. Calculate the molar mass of cobalt(II) phosphate by adding the atomic masses of all constituent atoms. 2. Determine the total mass of cobalt in the compound. 3. Divide the total mass of cobalt by the molar mass of the compound. 4. Multiply the result by 100 to get the percentage.
