**Question 4: What is the molecular weight of magnesium phosphite nonahydrate?** In educational contexts, understanding how to compute molecular weights is a fundamental skill in chemistry. Molecular weight, also known as molecular mass, is critical for stoichiometric calculations and various applications in chemical reactions and formulations. For the compound magnesium phosphite nonahydrate, the molecular formula can be determined, and each atomic mass can be summed to find the total molecular weight. **Steps to Calculate Molecular Weight:** 1. Identify the molecular formula of magnesium phosphite nonahydrate. 2. Determine the atomic masses of each element involved. 3. Multiply the number of atoms of each element by their respective atomic masses. 4. Add up all the atomic masses to get the total molecular weight. Example: For illustrative purposes, suppose the molecular formula is Mg₃(PO₃)₂·9H₂O. The respective atomic masses are approximately: - Magnesium (Mg): 24.305 g/mol - Phosphorus (P): 30.974 g/mol - Oxygen (O): 15.999 g/mol - Hydrogen (H): 1.008 g/mol **Molecular Calculation:** - Magnesium: 3 atoms × 24.305 g/mol = 72.915 g/mol - Phosphorus: 2 atoms × 30.974 g/mol = 61.948 g/mol - Oxygen in PO₃: 6 atoms × 15.999 g/mol = 95.994 g/mol - Additional Oxygen in 9H₂O: 9 atoms × 1 (from H₂O) × 15.999 g/mol = 143.991 g/mol - Hydrogen in 9H₂O: 9 atoms × 2 (per H₂O) × 1.008 g/mol = 18.144 g/mol **Summing these values:** 72.915 g/mol (Mg) + 61.948 g/mol (P) + 95.994 g/mol (O in PO₃) + 143.991 g/mol (O in 9H₂O) + 18.144 g/mol (H in 9H₂O) = 392.992 g/mol Thus, the total molecular weight of magnesium phosphite nonahydrate is approximately 392.992 g/mol. This example would instruct students on how
