Calculate the molar mass of methane.

Methane is a simple hydrocarbon with the chemical formula CH₄. To calculate its molar mass, we need to consider the atomic masses of its constituent elements: carbon (C) and hydrogen (H).

Components of Molar Mass

• Carbon (C): The atomic mass is approximately 12.01 g/mol.
• Hydrogen (H): The atomic mass is about 1.008 g/mol.

Calculating Molar Mass

The molar mass of methane can be calculated using the formula:

Molar Mass of CH₄ = (1 × Atomic Mass of C) + (4 × Atomic Mass of H)

Substituting Values

Now, substituting the values:

Molar Mass = (1 × 12.01 g/mol) + (4 × 1.008 g/mol)

Molar Mass = 12.01 g/mol + 4.032 g/mol

Final Result

Adding these together gives:

Molar Mass of CH₄ = 16.042 g/mol

Therefore, the molar mass of methane is approximately 16.04 g/mol.
