Understanding the Ratio of Carbon Atoms in Methane and Carbon Monoxide

Introduction

In the field of chemistry, understanding the ratio of carbon atoms in different compounds is crucial for various applications, from environmental science to industrial processes. A classic example is the comparison between methane (CH?) and carbon monoxide (CO), which are both significant carbon-based molecules. This article delves into the ratio of carbon atoms in 2 grams of methane to that in 2 grams of carbon monoxide, providing a clear explanation with scientific backing.

Understanding Molecules: Methane (CH?) and Carbon Monoxide (CO)

Methane (CH?) and carbon monoxide (CO) are two distinct molecules with separate structures and properties. Methane is a simple, flammable hydrocarbon gas that is a primary constituent of natural gas. Carbon monoxide, on the other hand, is a colorless, odorless, and toxic gas that results from partial oxidation of carbon.

Determining the Molar Masses of CH? and CO

To understand the ratio of carbon atoms in 2 grams of CH? and CO, it is important to first calculate their molar masses. The molar mass of a substance is the mass of one mole of that substance.

Methane (CH?):

Carbon (C): 12.01 g/mol Hydrogen (H): 1.008 g/mol

Molar mass of CH? 12.01 g/mol (C) 4 × 1.008 g/mol (H) 16.042 g/mol

Carbon Monoxide (CO):

Carbon (C): 12.01 g/mol Oxygen (O): 16.00 g/mol

Molar mass of CO 12.01 g/mol (C) 16.00 g/mol (O) 28.01 g/mol

Calculating the Number of Carbon Atoms in 2 G of CH? and CO

Once we have the molar masses, we can determine the number of moles of each substance in 2 grams.

Methane (CH?):

Number of moles in 2 grams of CH? 2 g / 16.042 g/mol ≈ 0.1247 moles

Number of carbon atoms in 2 grams of CH? 0.1247 moles × 6.022 × 1023 atoms/mole ≈ 7.51 × 1022 atoms

Carbon Monoxide (CO):

Number of moles in 2 grams of CO 2 g / 28.01 g/mol ≈ 0.07139 moles

Number of carbon atoms in 2 grams of CO 0.07139 moles × 6.022 × 1023 atoms/mole ≈ 4.31 × 1022 atoms

Calculating the Ratio of Carbon Atoms

Using the calculated number of carbon atoms, we can determine the ratio.

Step 1: Divide the number of carbon atoms in CH? by the number in CO.

Ratio (7.51 × 1022) / (4.31 × 1022) ≈ 1.74

Step 2: Simplify the ratio to the lowest common terms.

ratio of 1.74 can be expressed as 7:4.

Conclusion

To summarize, the ratio of the number of carbon atoms in 2 grams of methane (CH?) to that in 2 grams of carbon monoxide (CO) is 7:4. This ratio provides insight into the relative amounts of carbon atoms present in these two distinct compounds, essential for understanding their behavior in various chemical reactions and environmental contexts.
