Use the periodic table to calculate the molar mass of each of the following compounds Each answe must have 2 decimal places. Ammonia (NH3): (NH_(3)): g/mol Magnesium hydroxide (Mg(OH)2): g/mol Iron (III) oxide (Fe2O3): (Fe_(2)O_(3)): g/mol

# Explanation:## Step 1: Calculate the molar mass of Ammonia (NH₃)### For each element, multiply the atomic mass by the number of atoms in the compound, then sum the results:- N: - H: - Molar Mass of NH₃: ## Step 2: Calculate the molar mass of Magnesium Hydroxide (Mg(OH)₂)### For each element, multiply the atomic mass by the number of atoms in the compound, then sum the results:- Mg: - O: - H: - Molar Mass of Mg(OH)₂: ## Step 3: Calculate the molar mass of Iron(III) Oxide (Fe₂O₃)### For each element, multiply the atomic mass by the number of atoms in the compound, then sum the results:- Fe: - O: - Molar Mass of Fe₂O₃: # Answer:### Ammonia: 17.04 g/mol### Magnesium Hydroxide: 58.33 g/mol### Iron(III) Oxide: 159.70 g/mol
