▼

- Convert 56.0 g of N₂ to moles using its molar mass (28.0 g/mol): 56.0 g / 28.0 g/mol = 2.00 mol N₂.
- Use the mole ratio from the balanced equation (1 mol N₂ : 2 mol NH₃) to find moles of NH₃ produced: 2.00 mol N₂ × (2 mol NH₃ / 1 mol N₂) = 4.00 mol NH₃.
- Convert moles of NH₃ to grams using its molar mass (17.0 g/mol): 4.00 mol NH₃ × 17.0 g/mol = 68.0 g NH₃.

Parent Tip: Review the logic above to help your child master the concept of mass problems worksheet.
