Sample Mole Calculation Problem and Solution (Using the Answer Key)

Let's examine an example problem commonly found in chemistry courses:

Problem:

Calculate the number of moles in 24 grams of carbon dioxide (CO₂).

Solution Steps (as per ChemFiesta answer key):

1. Identify the known values:

Mass of CO₂ = 24 grams.

2. Calculate the molar mass of CO₂:

• Carbon (C) = 12.01 g/mol
• Oxygen (O) = 16.00 g/mol
• Molar mass of CO₂ = 12.01 + 2(16.00) = 44.01 g/mol.

3. Set up the calculation:

Number of moles = mass / molar mass.

4. Perform the calculation:

Number of moles = 24 g / 44.01 g/mol ≈ 0.545 mol.

5. Final Answer:

There are approximately 0.545 moles of CO₂ in 24 grams.

This example illustrates how the ChemFiesta answer key simplifies the process, providing clarity and confidence in your calculations.
