    Since both samples are pure CH4 (methane), the proportion of C to H that evolves from the decomposition should be equal. In equation form:

    35.0 g C / 2.04 g H = 23.0 g C / x g H

    Solving for x gives a value of x = 1.3406 g H

    So 1.3406 grams of hydrogen will be produced from sample b.
