Question

What is the molar mass of methane (CH₄)?
Options
A 14.00 g/mol
B 15.00 g/mol
C 16.04 g/mol
Correct Answer
D 17.02 g/mol
Correct Answer

Option C is the correct answer.

Detailed Explanation

Molar mass of CH₄ = atomic mass of C + (4 × atomic mass of H) = 12.01 + (4 × 1.008) = 12.01 + 4.032 = 16.042 g/mol, approximately 16.04 g/mol.

Hint

Add the atomic mass of carbon to four times the atomic mass of hydrogen.
