Answer
A. 353.59
Explanation
To solve this stoichiometry problem, we need to use the balanced chemical equation for the reaction between sodium phosphate (Na₃PO₄) and calcium chloride (CaCl₂). The balanced equation is:
Next, we convert the mass of CaCl₂ to moles, use the mole ratio from the balanced equation to find moles of Ca₃(PO₄)₂, and then convert moles of Ca₃(PO₄)₂ to grams.1. Calculate moles of CaCl₂:
2. Use the mole ratio to find moles of Ca₃(PO₄)₂:
3. Convert moles of Ca₃(PO₄)₂ to grams:
