2. MOLE TO MOLE CONVERSION
1 N2(g) H2(g) → 2 NH3(g)
How many moles of ammonia form when 0.60 moles of nitrogen react with an excess of hydrogen?

3. MOLE TO MOLE CONVERSION
1 N2(g) H2(g) → 2 NH3(g)
Calc. the no. of moles of H2 required to make 7.24 moles of ammonia.

4. MASS TO MASS CONVERSION
1 N2(g) + 3 H2(g) → 2 NH3(g)
Calc. the no. of grams of NH3 formed by the reaction of 5.40 grams of H2 with an excess of nitrogen.

5. MASS TO PARTICLE CONVERSION
2 H2O(l) → 2 H2(g) + O2(g)
How many molecules of O2 are formed when 29.2 g of water is decomposed?
