Steps to solve mole-to-mole problems: Step1: Write the balanced equation. Step2: Write the molar ratio. Step3: Look at the given and the required. Step4: Use the molar ratio to find the moles of the required compound.

2. What do we need to know to solve the mole to mole
problem:
• We need to know how to balance the chemical
equations.
• Extract the Mole ratio from the equation.
• Dimensional analysis.

3. Example -1:
Suppose we have 3.00 mol of N2 reacting with sufficient H2, how many
moles of NH3 will be produced?
Step1: Write the balanced equation.
Solution:

4. Step2: Write the molar ratio.
Step3: Look at the given and the required.
Suppose we have 3.00 mol of N2 reacting with sufficient H2, how many
moles of NH3 will be produced?
Step4: Use the molar ratio to find the moles of the required compound.
