Verified step by step guidance

Identify the given carbon-to-hydrogen mass ratio of the compound, which is 11.89.

Understand that the mass ratio is calculated by dividing the mass of carbon by the mass of hydrogen in the compound.

Recognize that the mass of carbon (C) is 12.01 g/mol and the mass of hydrogen (H) is 1.008 g/mol.

Calculate the possible mass ratios by considering different numbers of carbon and hydrogen atoms in a hypothetical compound. For example, for a compound with one carbon atom and one hydrogen atom, the mass ratio would be \( \frac{12.01}{1.008} \).

Compare the calculated mass ratios with the given options (3.00, 6.00, 4.00, 8.00) to determine which one is a feasible carbon-to-hydrogen mass ratio for a compound composed only of carbon and hydrogen.
